Qur’anic Root TH L TH

1. Introducing the root and its Qur’anic forms

The triliteral Arabic root TH L TH concerns the number three and its related forms. It produces words for counting three things, the third member of a set, one-third of a given quantity, dividing something into three parts, and arranging people or objects in groups of three.

In the Qur’an, this root occurs in varied settings: three days of fasting, three waiting periods, three months, three occasions for requesting permission, one-third and two-thirds of an inheritance, portions of the night, three messengers, three groups on the Day of Resurrection, three darknesses in human creation, and the critique of threefold claims about divinity.

This variety shows that three in the Qur’an does not belong exclusively to one religious subject or symbolic idea. Sometimes it is an actual quantity, sometimes a share of a whole, sometimes a member’s position among others, and sometimes part of a construction expressing grouping and distribution.

The root TH L TH occurs 32 times in 28 verses across 20 surahs. All its Qur’anic occurrences are nominal or numerical; no independent verb from this root occurs in the Qur’an.

Important forms in this family include:

• ثَلَاثَة (thalāthah): three; the numeral normally used with a grammatically masculine counted noun. Qur’anic use: yes, thirteen occurrences in its various forms.
• ثَلَاث (thalāth): three; the numeral normally used with a grammatically feminine counted noun. Qur’anic use: yes, eight occurrences, including the constructions for thirty and three hundred.
• ثَالِث (thālith): third; the third member or one member of a three-member set. Qur’anic use: yes, twice, in Al-Māʾidah 5:73 and Yā Sīn 36:14.
• ثَالِثَة (thālithah): third; the feminine ordinal. Qur’anic use: yes, once, in Al-Najm 53:20.
• ثُلَاث (thulāth): three at a time, or in groups of three. Qur’anic use: yes, twice, in Al-Nisāʾ 4:3 and Fāṭir 35:1.
• ثُلُث (thuluth): one-third of a quantity or whole. Qur’anic use: yes, six occurrences together with its dual forms.
• ثُلُثَان / ثُلُثَا / ثُلُثَيْنِ (thuluthān / thuluthā / thuluthayn): two-thirds; two of three equal parts. Qur’anic use: yes, in forms governed by dual morphology.
• ثَلَاثُون / ثَلَاثِينَ (thalāthūn / thalāthīn): thirty; a multiple of ten. Qur’anic use: yes, in Al-Aʿrāf 7:142 and Al-Aḥqāf 46:15.
• ثَلَثَ / يَثْلِثُ / يَثْلُثُ (thalatha / yathlithu / yathluthu): with kasrah on the present-tense lām, to become the third member or make two people three; with ḍammah, to take one-third of property. Qur’anic use: no.
• ثَلَّثَ / تَثْلِيث (thallatha / tathlīth): to make three, divide into three parts, or make something threefold. Qur’anic use: no.
• أَثْلَثَ (athlatha): to become three, make three parts, or reach a third stage. Qur’anic use: no.
• ثَالُوث (thālūth): a triad; also a term used in theological discussion. Qur’anic use: no.
• ثُلَاثِيّ (thulāthī): consisting of three parts or three letters. Qur’anic use: no.
• الثُّلَاثَاء (al-thulāthāʾ): the name of a weekday, Tuesday. Qur’anic use: no.

These forms show that the root’s linguistic family extends beyond its Qur’anic forms.

Quranic Arabic Corpus: thirty-two occurrences of TH L TH

Three matters must nevertheless be distinguished: the number three, third position, and the fraction one-third. Sharing a root does not make these concepts identical.

2. The linguistic core and older Arabic usage

Three: a definite quantity

In Arabic, thalāthah and thalāth name the number three.

In counting, three is a quantity greater than two and smaller than four. This simple definition underlies the root’s numerical uses.

In Maqāyīs al-Lughah, Ibn Fāris identifies a numerical origin for TH L TH. Unlike roots whose semantic fields extend across several physical and abstract images, this root is fundamentally based on number and the ratios derived from it.

Maqāyīs al-Lughah: the numerical origin of TH L TH

Different forms can be built from the number three.

“Three people” states a group’s membership count. “The third person” identifies someone’s place in an ordering. “One-third of the property” identifies a proportion of the total property.

These three expressions belong to one numerical family, but differ in meaning and use.

“Three times” also differs from “three people.” One counts repetitions of an action; the other counts people.

The number’s meaning therefore remains constant, while what it counts changes its role in the sentence.

Becoming the third member

In Arabic, thalatha al-qawma can mean joining a group and becoming its third member.

For example, if two people are present and a third joins them, the group’s number has reached three through that person.

Here the verb concerns adding a third member.

This meaning, however, is not precisely identical to thālithu thalāthatin.

“A third person added to two” highlights the process of joining the group. Thālithu thalāthatin can simply identify a member’s position in a three-person set without saying when its members joined.

This distinction matters when examining Al-Māʾidah 5:73 and Yā Sīn 36:14.

One-third and dividing a quantity

Thuluth in Arabic denotes one of three equal parts.

If property is divided into three equal shares, each share is one-third.

Thuluthān denotes two of those same three equal shares.

In this field, three no longer directly counts people or objects; it provides the basis for dividing a whole.

The same family supplies verbs for taking one-third of property, dividing something into three parts, and making a set threefold.

The verb thalatha in the sense of taking one-third does not occur in the Qur’an.

Al-Ṣiḥāḥ and Al-Miṣbāḥ: yathlithu and yathluthu

The presence of thuluth in inheritance verses therefore does not establish an independent, general Qur’anic rule allowing one-third to be taken from every kind of property.

The one-third share in each verse depends on specified conditions and people.

Physical images: three supports and three strands

This root has no independent primary physical image such as cutting, pulling, or turning. Three nevertheless appears in the naming of actual objects.

One familiar older Arabic example is thālithatu al-athāfī.

Athāfī are stones supporting a cooking pot over a fire. In a traditional arrangement, two stones were placed alongside a third stone or a natural projection of the ground that completed the third support.

This is the setting behind the familiar expression thālithatu al-athāfī.

Here three concerns the number of supports.

Arabic also records braiding or twisting a rope from three strands.

In that example, three components together form a physical structure.

These examples do not establish stability, strength, or perfection as the primary meaning of three.

One object may stand firmly on three supports and another on four or five. The number itself guarantees none of these qualities.

Three supports or strands help illustrate the number’s physical applications, while the root’s definition remains numerical.

3. Evidence from older Arabic poetry

In his lexical transmission of this witness, Ibn Barrī attributes it to ʿAbd Allāh ibn al-Zubayr al-Asadī:

فَإِنْ تَثْلِثُوا نَرْبَعْ وَإِنْ يَكُ خَامِسٌ
يَكُنْ سَادِسٌ حَتَّى يُبِيرَكُمُ الْقَتْلُ

fa-in tathlithū narbaʿ wa-in yaku khāmisun / yakun sādisun ḥattā yubīrakumu al-qatlu

English translation

If your number reaches three, we shall make ours four; and if there is a fifth, there will be a sixth, until the killing destroys you.

In this line, tathlithū and narbaʿ concern increasing the membership of two groups.

The poet speaks in a setting of rivalry and confrontation: whenever one group’s number increases, the other increases its own.

Some lexical explanations also offer another reading of tathlithū, connecting it with killing a third person.

The main numerical explanation, however, is increasing group membership, especially since the following line continues the sequence through seven, eight, nine, and ten.

This witness shows that a verb can be formed from three and used for a count reaching its third stage.

The line’s precise date of composition is not independently established. It should therefore not be presented as a securely pre-Islamic witness without examining the poet’s history and the poem itself.

Al-Ṣiḥāḥ with Ibn Barrī’s transmission: attribution of the poetic witness

Elsewhere in Arabic poetic language, thālithatu al-athāfī denotes the third stone or component completing the pot’s three-support arrangement.

This usage shows that the ordinal thālith is not restricted to people: it can identify an object’s place in a three-part structure.

Taken together, the witnesses confirm the numerical core: a count of three, third position, and dividing a whole into three parts.

They do not show that three always symbolized holiness or absolute perfection in older Arabic.

4. Three and three at a time: thalāthah and thulāth

Al-Nisāʾ 4:3

Verse text

وَإِنْ خِفْتُمْ أَلَّا تُقْسِطُوا فِي الْيَتَامَىٰ فَانْكِحُوا مَا طَابَ لَكُمْ مِنَ النِّسَاءِ مَثْنَىٰ وَثُلَاثَ وَرُبَاعَ فَإِنْ خِفْتُمْ أَلَّا تَعْدِلُوا فَوَاحِدَةً أَوْ مَا مَلَكَتْ أَيْمَانُكُمْ ذَٰلِكَ أَدْنَىٰ أَلَّا تَعُولُوا

wa-in khiftum allā tuqsiṭū fī al-yatāmā fa-inkiḥū mā ṭāba lakum mina al-nisāʾi mathnā wa-thulātha wa-rubāʿa fa-in khiftum allā taʿdilū fa-wāḥidatan aw mā malakat aymānukum dhālika adnā allā taʿūlū

English translation

If you fear that you will not act justly toward orphans, then marry such women as are agreeable to you, in twos, threes, and fours. But if you fear that you will not maintain justice, then one, or those under your authority. That is nearer to your not departing from justice.

Examining the usage

Thulātha in this verse differs from thalāthah.

Thalāthah names the number three, whereas thulāth in this construction expresses distributive number: three at a time or in groups of three.

Arabic forms such as mathnā, thulātha, and rubāʿ express numerical distribution.

In this sentence, the construction does not mean the arithmetic sum of two, three, and four.

Mathnā wa-thulātha wa-rubāʿ therefore does not yield the intended number nine by adding two, three, and four.

Nor should the distributive construction be translated as though each addressee must carry out all three possibilities simultaneously.

Linguistically, the expression presents different numerical arrangements.

The verse’s subject, however, is not number alone.

It begins with the condition “if you fear that you will not act justly toward orphans,” and later states the condition of justice and returning to one wife.

The marriage ruling must therefore be examined in relation to orphans, justice, and family responsibilities.

Thulāth alone cannot establish an unrestricted right independent of these conditions.

Equally, the number’s distributive form alone does not determine every limit of the ruling or every actual condition of marriage.

Forqan’s separate article on polygamy examines this issue in the context of justice toward orphans and women’s rights. The root study reaches a narrower conclusion: thulāth is the distributive form of three and must not be confused with an arithmetic sum or an unrestricted permission.

Polygamy in the Qur’an

Fāṭir 35:1: threes in the description of angels’ wings

Verse text

الْحَمْدُ لِلَّهِ فَاطِرِ السَّمَاوَاتِ وَالْأَرْضِ جَاعِلِ الْمَلَائِكَةِ رُسُلًا أُولِي أَجْنِحَةٍ مَثْنَىٰ وَثُلَاثَ وَرُبَاعَ يَزِيدُ فِي الْخَلْقِ مَا يَشَاءُ إِنَّ اللَّهَ عَلَىٰ كُلِّ شَيْءٍ قَدِيرٌ

Al-ḥamdu li-llāhi fāṭiri s-samāwāti wa-l-arḍi jāʿili l-malāʾikati rusulan ulī ajniḥatin mathnā wa-thulātha wa-rubāʿa yazīdu fī l-khalqi mā yashāʾu inna llāha ʿalā kulli shayʾin qadīr.

English translation

Praise belongs to The God, Originator of the heavens and the earth, who makes the angels messengers possessing wings in twos, threes, and fours. He adds to creation whatever He wills. The God is indeed capable of all things.

Examining the usage

The same construction, mathnā wa-thulātha wa-rubāʿ, occurs here.

Its subject differs from Al-Nisāʾ 4:3.

In Al-Nisāʾ these forms occur in a marriage context; in Fāṭir they describe angels’ wings.

This comparison shows that thulāth itself does not express a marriage ruling, a number of wives, or a family relationship.

It simply supplies the distributive counting form.

In Fāṭir 35:1, too, adding two, three, and four does not establish that every angel has exactly nine wings.

The phrase “He adds to creation whatever He wills” also follows these numbers. These three quantities alone therefore cannot establish an absolute ceiling for all divine creation.

The description of wings raises another point.

Thulāth does not reveal the precise bodily shape, material, size, or function of angels’ wings.

The verse itself does not explain these matters.

Lexical conclusion: In both verses, thulāth is the distributive form of three. Its different applications to marriage and angels’ wings show that the word’s meaning remains constant, while the subject’s rulings and characteristics require their own contextual examination.

5. Thālith: third position in a set

Yā Sīn 36:14: the third messenger

Verse text

إِذْ أَرْسَلْنَا إِلَيْهِمُ اثْنَيْنِ فَكَذَّبُوهُمَا فَعَزَّزْنَا بِثَالِثٍ فَقَالُوا إِنَّا إِلَيْكُمْ مُرْسَلُونَ

idh arsalnā ilayhimu ithnayni fa-kadhdhabūhumā fa-ʿazzaznā bi-thālithin fa-qālū innā ilaykum mursalūna

English translation

When We sent two to them, they denied them both; then We reinforced them with a third. They said, “We have indeed been sent to you.”

Examining the usage

Bi-thālithin refers to a third person.

Here the first two messengers are introduced, and a third is then added to them.

Thālith in this context therefore concerns adding a member to an existing set.

The ordinal identifies his place in the messengers’ count.

The word itself does not mean strengthening or helping. Strengthening comes from the verb fa-ʿazzaznā.

The sentence’s entire meaning should therefore not be compressed into thālith.

Nor does three establish that every divine mission must involve three messengers.

The number concerns a particular event.

Al-Māʾidah 5:73: thālithu thalāthatin

Verse text

لَقَدْ كَفَرَ الَّذِينَ قَالُوا إِنَّ اللَّهَ ثَالِثُ ثَلَاثَةٍ وَمَا مِنْ إِلَٰهٍ إِلَّا إِلَٰهٌ وَاحِدٌ وَإِنْ لَمْ يَنْتَهُوا عَمَّا يَقُولُونَ لَيَمَسَّنَّ الَّذِينَ كَفَرُوا مِنْهُمْ عَذَابٌ أَلِيمٌ

la-qad kafara alladhīna qālū inna Allāha thālithu thalāthatin wa-mā min ilāhin illā ilāhun wāḥidun wa-in lam yantahū ʿammā yaqūlūna la-yamassanna alladhīna kafarū minhum ʿadhābun alīmun

English translation

Those who said that The God is the third of three have certainly disbelieved, although there is no deity except one deity. If they do not stop what they are saying, a painful punishment will surely touch those among them who have disbelieved.

Examining the usage

Grammatically, thālithu thalāthatin differs from bi-thālithin in Yā Sīn 36:14.

In Yā Sīn, a third person is added to the two earlier messengers.

In thālithu thalāthatin, however, the third is identified as a member of a three-member set.

This distinction is recognized in Arabic.

Thālithu thalāthatin need not describe someone who arrived later than two others; it can identify one member of the set of three.

In Al-Māʾidah 5:73, the Qur’an uses this form while reporting and criticizing a claim about The God.

The criticism concerns including The God in a threefold enumeration at the level of divinity.

The following expression clarifies this:

“There is no deity except one deity.”

The verse emphasizes the deity’s oneness.

Thālithu thalāthatin alone nevertheless does not reveal every detail of a historical theological system or the precise names of all three alleged components.

This expression does not name the three.

Their not being named should equally not make the Qur’an’s explicit critique of making divinity threefold vague or ineffective.

Lexical conclusion: In both verses, thālith concerns the third member or third position. In Yā Sīn, a third person joins two others; in Al-Māʾidah, the claim of placing The God within a threefold set is criticized.

Al-Najm 53:20: third among the named deities

Al-Najm 53:19 and Al-Najm 53:20 name al-Lāt, al-ʿUzzā, and Manāt.

Of Manāt, the text says:

وَمَنَاةَ الثَّالِثَةَ الْأُخْرَىٰ

wa-Manāta al-thālithata al-ukhrā

English translation

And Manāt, the other, the third.

Al-thālithah is the feminine ordinal “third.”

Here it identifies Manāt’s position in the list of names mentioned.

The word itself does not establish Manāt’s rank of divinity, superiority, or historical standing relative to the other two names.

In this context, “third” is primarily a position in counting.

6. Threefold claims in matters of belief

Al-Nisāʾ 4:171

Verse text

يَا أَهْلَ الْكِتَابِ لَا تَغْلُوا فِي دِينِكُمْ وَلَا تَقُولُوا عَلَى اللَّهِ إِلَّا الْحَقَّ إِنَّمَا الْمَسِيحُ عِيسَى ابْنُ مَرْيَمَ رَسُولُ اللَّهِ وَكَلِمَتُهُ أَلْقَاهَا إِلَىٰ مَرْيَمَ وَرُوحٌ مِنْهُ فَآمِنُوا بِاللَّهِ وَرُسُلِهِ وَلَا تَقُولُوا ثَلَاثَةٌ انْتَهُوا خَيْرًا لَكُمْ إِنَّمَا اللَّهُ إِلَٰهٌ وَاحِدٌ سُبْحَانَهُ أَنْ يَكُونَ لَهُ وَلَدٌ لَهُ مَا فِي السَّمَاوَاتِ وَمَا فِي الْأَرْضِ وَكَفَىٰ بِاللَّهِ وَكِيلًا

yā ahla al-kitābi lā taghlū fī dīnikum wa-lā taqūlū ʿalā Allāhi illā al-ḥaqqa innamā al-Masīḥu ʿĪsā ibnu Maryama rasūlu Allāhi wa-kalimatuhu alqāhā ilā Maryama wa-rūḥun minhu fa-āminū bi-Allāhi wa-rusulihi wa-lā taqūlū thalāthatun intahū khayran lakum innamā Allāhu ilāhun wāḥidun subḥānahu an yakūna lahu waladun lahu mā fī al-samāwāti wa-mā fī al-arḍi wa-kafā bi-Allāhi wakīlan

English translation

People of the Scripture, do not exceed bounds in your religion, and say nothing about The God except the truth. The Messiah, Jesus son of Mary, is only the messenger of The God and His word, which He cast to Mary, and a spirit from Him. So believe in The God and His messengers, and do not say “three.” Desist; that is better for you. The God is only one deity, exalted above having a child. To Him belongs whatever is in the heavens and the earth, and The God suffices as guardian and trustee.

Examining the usage

Thalāthatun here is the number three, but the counted noun is not explicitly supplied in the same expression.

The command reads:

“Do not say ‘three.’”

Linguistically, the expression prohibits uttering or asserting a threefold claim.

Its subject must nevertheless be identified from context.

The verse first prohibits religious excess and saying what is untrue about The God. It then speaks of the Messiah, Jesus son of Mary, his position as messenger, the word of The God, and a spirit from Him, before saying “do not say three.”

Its subject is therefore not an abstract number unrelated to belief, but a threefold claim concerning divinity and Jesus’ relationship with The God.

The word thalāthah itself nevertheless does not determine precisely which persons or concepts constitute the alleged three.

This numeral alone cannot establish one particular historical formula for every addressee of the verse.

The verse, however, states a clear monotheistic conclusion:

“The God is only one deity.”

The Qur’an thus rejects making divinity threefold in a way incompatible with the oneness of The God.

The lexical meaning of thalāthah remains three. Associating partners, excess, and false attribution to The God arise from the verse’s doctrinal context, rather than from any inherently negative meaning of three.

Threefold claims and ordinary counting

Elsewhere, the same Qur’an speaks of three days, three months, three groups, and three messengers.

Three in itself is therefore neither objectionable nor a sign of associating partners with The God.

What Al-Nisāʾ 4:171 and Al-Māʾidah 5:73 criticize is placing divinity within a threefold structure.

This distinction prevents every three-part arrangement, such as three stages of a task or three characteristics of a phenomenon, from being condemned on religious grounds.

Conversely, defending a system of belief should not reduce the Qur’an’s explicit criticism to a question of arithmetic counting alone.

The Qur’an is speaking about The God and attributing a partner or equal to Him.

The doctrinal discussion is therefore real in its own setting, while remaining distinct from the lexical meaning of three.

7. Thuluth and thuluthān: one-third and two-thirds in inheritance

Al-Nisāʾ 4:11

Verse text

يُوصِيكُمُ اللَّهُ فِي أَوْلَادِكُمْ لِلذَّكَرِ مِثْلُ حَظِّ الْأُنْثَيَيْنِ فَإِنْ كُنَّ نِسَاءً فَوْقَ اثْنَتَيْنِ فَلَهُنَّ ثُلُثَا مَا تَرَكَ وَإِنْ كَانَتْ وَاحِدَةً فَلَهَا النِّصْفُ وَلِأَبَوَيْهِ لِكُلِّ وَاحِدٍ مِنْهُمَا السُّدُسُ مِمَّا تَرَكَ إِنْ كَانَ لَهُ وَلَدٌ فَإِنْ لَمْ يَكُنْ لَهُ وَلَدٌ وَوَرِثَهُ أَبَوَاهُ فَلِأُمِّهِ الثُّلُثُ فَإِنْ كَانَ لَهُ إِخْوَةٌ فَلِأُمِّهِ السُّدُسُ مِنْ بَعْدِ وَصِيَّةٍ يُوصِي بِهَا أَوْ دَيْنٍ آبَاؤُكُمْ وَأَبْنَاؤُكُمْ لَا تَدْرُونَ أَيُّهُمْ أَقْرَبُ لَكُمْ نَفْعًا فَرِيضَةً مِنَ اللَّهِ إِنَّ اللَّهَ كَانَ عَلِيمًا حَكِيمًا

yūṣīkumu allāhu fī awlādikum li-l-dhakari mithlu ḥaẓẓi al-unthayayni fa-in kunna nisāʾan fawqa ithnatayni fa-lahunna thuluthā mā taraka wa-in kānat wāḥidatan fa-lahā al-niṣfu wa-li-abawayhi li-kulli wāḥidin minhumā al-sudusu mimmā taraka in kāna lahu waladun fa-in lam yakun lahu waladun wa-warithahu abawāhu fa-li-ummihi al-thuluthu fa-in kāna lahu ikhwatun fa-li-ummihi al-sudusu min baʿdi waṣiyyatin yūṣī bihā aw daynin ābāʾukum wa-abnāʾukum lā tadrūna ayyuhum aqrabu lakum nafʿan farīḍatan mina allāhi inna allāha kāna ʿalīman ḥakīmā

English translation

The God instructs you concerning your children: for a male, a share equal to that of two females. If they are daughters numbering more than two, theirs is two-thirds of what is left; if there is one daughter, hers is half. For each parent, one-sixth of what is left if the deceased has a child. If he has no child and his parents inherit from him, his mother has one-third; if he has brothers or sisters, his mother has one-sixth, after a bequest he makes or a debt. Your parents and your children: you do not know which are nearer to you in benefit. This is an obligation from The God. The God is indeed Knowing and Wise.

Examining the usage

This verse contains thuluthā and al-thuluthu from TH L TH.

Thuluthā is the dual of thuluth in the nominative construct form.

It means two-thirds: two of three equal shares.

Al-thuluthu denotes one-third.

Lexically, one-third and two-thirds therefore have a clear mathematical distinction.

Identifying which person receives which share, however, requires more than knowing the fraction itself.

In this verse, shares depend on the presence and number of children, the parents’ situation, and the presence of sisters or brothers.

The number gives the share’s quantity; eligibility conditions belong to the structure of the ruling.

Another point concerns fawqa ithnatayni.

Literally, this expression means “more than two.”

Al-Nisāʾ 4:176, by comparison, explicitly says of two sisters:

“If there are two, theirs is two-thirds.”

These expressions should not be merged without examining their different subjects and grammatical constructions.

Al-Nisāʾ 4:11 concerns children, while Al-Nisāʾ 4:176 occurs in the context of kalālah and sisters.

Determining all inheritance shares therefore requires an independent study of the inheritance verses, beyond identifying TH L TH.

Al-Nisāʾ 4:12: a shared one-third

Al-Nisāʾ 4:12 also states:

“They share in the one-third.”

Here al-thuluth identifies a one-third share.

Shurakāʾ, however, indicates several people sharing that portion.

Thuluth itself therefore does not mean that each person separately receives one-third of the entire estate.

A shared one-third differs from one-third for each individual.

The same verse also connects inheritance distribution with bequests, debts, and the restriction against causing harm.

Number and share thus form part of a larger legal structure.

Al-Nisāʾ 4:176: two-thirds for two sisters

Verse text

يَسْتَفْتُونَكَ قُلِ اللَّهُ يُفْتِيكُمْ فِي الْكَلَالَةِ إِنِ امْرُؤٌ هَلَكَ لَيْسَ لَهُ وَلَدٌ وَلَهُ أُخْتٌ فَلَهَا نِصْفُ مَا تَرَكَ وَهُوَ يَرِثُهَا إِنْ لَمْ يَكُنْ لَهَا وَلَدٌ فَإِنْ كَانَتَا اثْنَتَيْنِ فَلَهُمَا الثُّلُثَانِ مِمَّا تَرَكَ وَإِنْ كَانُوا إِخْوَةً رِجَالًا وَنِسَاءً فَلِلذَّكَرِ مِثْلُ حَظِّ الْأُنْثَيَيْنِ يُبَيِّنُ اللَّهُ لَكُمْ أَنْ تَضِلُّوا وَاللَّهُ بِكُلِّ شَيْءٍ عَلِيمٌ

yastaftūnaka quli Allāhu yuftīkum fī al-kalālati ini imruʾun halaka laysa lahu waladun wa-lahu ukhtun fa-lahā niṣfu mā taraka wa-huwa yarithuhā in lam yakun lahā waladun fa-in kānatā ithnatayni fa-lahumā al-thuluthāni mimmā taraka wa-in kānū ikhwatan rijālan wa-nisāʾan fa-li-al-dhakari mithlu ḥaẓẓi al-unthayayni yubayyinu Allāhu lakum an taḍillū wa-Allāhu bi-kulli shayʾin ʿalīmun

English translation

They ask you for a ruling. Say, “The God clarifies the ruling for you concerning kalālah: if a person dies without a child and has a sister, hers is half of what he leaves; he likewise inherits from her if she has no child. If there are two sisters, theirs is two-thirds of what is left. If there are brothers and sisters, male and female, a male receives a share equal to that of two females.” The God makes this clear to you so that you do not go astray. The God knows all things.

Examining the usage

Al-thuluthāni here is the definite dual form.

It means two-thirds; in this context, the share belongs to two sisters.

The number of heirs must therefore be distinguished from the fractional share.

Two sisters counts people; two-thirds expresses a financial proportion.

The two expressions belong to numerical families associated with two and three, but serve different functions.

The verse also states this two-thirds share under specified conditions. Without examining the other verses, it cannot be generalized to every inheritance situation involving two heirs.

Lexical conclusion: Thuluth is one-third and thuluthān is two-thirds. These forms express numerical ratios. Identifying the recipients, the priority of bequests and debts, and the demands of justice depends on the other components of the inheritance verses.

8. One-third and two-thirds in measuring the night

Al-Muzzammil 73:20

Verse text

إِنَّ رَبَّكَ يَعْلَمُ أَنَّكَ تَقُومُ أَدْنَىٰ مِنْ ثُلُثَيِ اللَّيْلِ وَنِصْفَهُ وَثُلُثَهُ وَطَائِفَةٌ مِنَ الَّذِينَ مَعَكَ وَاللَّهُ يُقَدِّرُ اللَّيْلَ وَالنَّهَارَ عَلِمَ أَنْ لَنْ تُحْصُوهُ فَتَابَ عَلَيْكُمْ فَاقْرَءُوا مَا تَيَسَّرَ مِنَ الْقُرْآنِ عَلِمَ أَنْ سَيَكُونُ مِنْكُمْ مَرْضَىٰ وَآخَرُونَ يَضْرِبُونَ فِي الْأَرْضِ يَبْتَغُونَ مِنْ فَضْلِ اللَّهِ وَآخَرُونَ يُقَاتِلُونَ فِي سَبِيلِ اللَّهِ فَاقْرَءُوا مَا تَيَسَّرَ مِنْهُ وَأَقِيمُوا الصَّلَاةَ وَآتُوا الزَّكَاةَ وَأَقْرِضُوا اللَّهَ قَرْضًا حَسَنًا وَمَا تُقَدِّمُوا لِأَنْفُسِكُمْ مِنْ خَيْرٍ تَجِدُوهُ عِنْدَ اللَّهِ هُوَ خَيْرًا وَأَعْظَمَ أَجْرًا وَاسْتَغْفِرُوا اللَّهَ إِنَّ اللَّهَ غَفُورٌ رَحِيمٌ

inna rabbaka yaʿlamu annaka taqūmu adnā min thuluthayi al-layli wa-niṣfahu wa-thuluthahu wa-ṭāʾifatun mina alladhīna maʿaka wa-Allāhu yuqaddiru al-layla wa-al-nahāra ʿalima an lan tuḥṣūhu fa-tāba ʿalaykum fa-iqraʾū mā tayassara mina al-qurʾāni ʿalima an sa-yakūnu minkum marḍā wa-ākharūna yaḍribūna fī al-arḍi yabtaghūna min faḍli Allāhi wa-ākharūna yuqātilūna fī sabīli Allāhi fa-iqraʾū mā tayassara minhu wa-aqīmū al-ṣalāta wa-ātū al-zakāta wa-aqriḍū Allāha qarḍan ḥasanan wa-mā tuqaddimū li-anfusikum min khayrin tajidūhu ʿinda Allāhi huwa khayran wa-aʿẓama ajran wa-istaghfirū Allāha inna Allāha ghafūrun raḥīmun

English translation

Your Lord knows that you stand for less than two-thirds of the night, and half of it, and one-third of it, as does a group of those with you. The God measures the night and the day. He knew that you would not measure it precisely, so He turned toward you; therefore recite what is feasible for you of the Qur’an. He knew that some of you would be ill, others would travel through the land seeking the bounty of The God, and others would fight in His way. So recite what is feasible for you of the Qur’an, establish ṣalāt, give zakāt, and lend The God a good loan. Whatever good you send ahead for yourselves, you will find it with The God, better and greater in reward. Seek forgiveness from The God. The God is indeed Forgiving and Merciful.

Examining the usage

This verse contains two forms from TH L TH:

Thuluthayi al-layli and thuluthahu.

The first is two-thirds of the night; the second is one-third of it.

Both express proportions of a temporal whole.

Here that whole is the night.

One-third of the night and one-third of an inheritance have the same mathematical ratio, but concern entirely different subjects and accompanying rulings.

The inheritance verses divide a financial share; Al-Muzzammil measures the duration of the night.

Thuluth itself therefore means neither property nor worship; it expresses the fraction one-third.

Are the three amounts added together?

The verse places two-thirds, half, and one-third alongside one another.

They should not be added together without justification to conclude that the addressee was required to stand longer than a whole night.

The expression concerns the durations of night vigil and their measurement.

The different fractions can describe different amounts on different nights or different circumstances of standing.

Each fraction must therefore be understood in its grammatical position.

The verse also acknowledges the difficulty of measuring the night precisely and then introduces relief for its addressees.

Al-Ṭabarī on Al-Muzzammil 73:20: less than two-thirds and vigil durations

Forqan’s published study of naskh in the Qur’an also examines this subject.

Naskh in the Qur’an

The point relevant to TH L TH is narrower: one-third and two-thirds are real measurements, but they alone cannot establish a fixed, universal timetable of night worship without considering context.

9. Three periods, months, and days: number in temporal responsibilities

Al-Baqarah 2:228: three qurūʾ

Al-Baqarah 2:228 states:

“Divorced women shall wait concerning themselves for three qurūʾ.”

Thalāthata in this expression is the number three.

Qurūʾ belongs to Q R ʾ and concerns periods associated with women’s menstruation and purity.

Three specifies the number of periods; it does not itself determine whether qurūʾ means menstruation, purity, or a transition between these states.

That difference must be examined in the study of the word itself and the verse’s context.

Thalāthah therefore does not establish that three qurūʾ necessarily equal three calendar months.

Al-Ṭalāq 65:4 speaks of thalāthatu ashhurin, but its counted noun differs from thalāthata qurūʾin.

Al-Ṭalāq 65:4: three months

Verse text

وَاللَّائِي يَئِسْنَ مِنَ الْمَحِيضِ مِنْ نِسَائِكُمْ إِنِ ارْتَبْتُمْ فَعِدَّتُهُنَّ ثَلَاثَةُ أَشْهُرٍ وَاللَّائِي لَمْ يَحِضْنَ وَأُولَاتُ الْأَحْمَالِ أَجَلُهُنَّ أَنْ يَضَعْنَ حَمْلَهُنَّ وَمَنْ يَتَّقِ اللَّهَ يَجْعَلْ لَهُ مِنْ أَمْرِهِ يُسْرًا

wa-allāʾī yaʾisna mina al-maḥīḍi min nisāʾikum ini irtabtum fa-ʿiddatuhunna thalāthatu ashhurin wa-allāʾī lam yaḥiḍna; wa-ulātu al-aḥmāli ajaluhunna an yaḍaʿna ḥamlahunna; wa-man yattaqi allāha yajʿal lahu min amrihi yusrā

English translation

For those of your women who have despaired of menstruation, if you are uncertain, their waiting period is three months; and likewise for those who have not menstruated. For pregnant women, the end of their term is when they deliver their pregnancy. Whoever is mindful of The God, He will bring ease in that person’s affairs.

Examining the usage

Thalāthatu ashhurin denotes three months.

The verse nevertheless addresses different groups, and pregnancy has a separate provision.

The meaning of three is clear, but identifying precisely whom the ruling applies to cannot be derived from the number alone.

Nor can thalāthatu ashhurin alone establish conclusions about marriage age, maturity, or the conditions of a valid marriage.

These issues must be examined with the verses on maturity, responsibility, marriage, and women’s circumstances.

Three is a temporal quantity, not a definition of marriage age or eligibility.

Maryam 19:10 and Āl ʿImrān 3:41: three nights and three days

In Maryam 19:10, Zechariah asks for a sign. The answer is not speaking to people for thalātha layālin sawiyyan, three nights while sound.

Āl ʿImrān 3:41 describes the same subject as thalāthata ayyāmin illā ramzan, three days except by gesture.

One mentions three nights, the other three days.

This difference should not be declared a contradiction or two wholly separate events without examination.

Arabic can use day and night to describe a continuous period; each verse nevertheless requires attention to its duration and qualifications.

Sawiyyan and illā ramzan also matter for grammar and the nature of not speaking, but do not belong to TH L TH.

Hūd 11:65: a three-day reprieve

In Hūd 11:65, after the she-camel is hamstrung, Ṣāliḥ’s people are told to enjoy themselves in their homes for three days.

Thalāthata ayyāmin here states a definite period.

Three itself does not explain why this duration was chosen or all its historical consequences.

Al-Nūr 24:58: three occasions for requesting permission

Verse text

يَا أَيُّهَا الَّذِينَ آمَنُوا لِيَسْتَأْذِنْكُمُ الَّذِينَ مَلَكَتْ أَيْمَانُكُمْ وَالَّذِينَ لَمْ يَبْلُغُوا الْحُلُمَ مِنْكُمْ ثَلَاثَ مَرَّاتٍ مِنْ قَبْلِ صَلَاةِ الْفَجْرِ وَحِينَ تَضَعُونَ ثِيَابَكُمْ مِنَ الظَّهِيرَةِ وَمِنْ بَعْدِ صَلَاةِ الْعِشَاءِ ثَلَاثُ عَوْرَاتٍ لَكُمْ لَيْسَ عَلَيْكُمْ وَلَا عَلَيْهِمْ جُنَاحٌ بَعْدَهُنَّ طَوَّافُونَ عَلَيْكُمْ بَعْضُكُمْ عَلَىٰ بَعْضٍ كَذَٰلِكَ يُبَيِّنُ اللَّهُ لَكُمُ الْآيَاتِ وَاللَّهُ عَلِيمٌ حَكِيمٌ

yā ayyuhā alladhīna āmanū li-yastaʾdhinkumu alladhīna malakat aymānukum wa-alladhīna lam yablughū al-ḥuluma minkum thalātha marrātin min qabli ṣalāti al-fajri wa-ḥīna taḍaʿūna thiyābakum mina al-ẓahīrati wa-min baʿdi ṣalāti al-ʿishāʾi thalāthu ʿawrātin lakum laysa ʿalaykum wa-lā ʿalayhim junāḥun baʿdahunna ṭawwāfūna ʿalaykum baʿḍukum ʿalā baʿḍin kadhālika yubayyinu Allāhu lakumu al-āyāti wa-Allāhu ʿalīmun ḥakīmun

English translation

You who have believed, let those under your authority and those among you who have not reached puberty ask your permission on three occasions: before the dawn ṣalāt, when you put aside your clothes at midday, and after the night ṣalāt. These are three times of privacy for you. Beyond them, there is no blame upon you or them: you regularly circulate among one another. Thus The God clarifies the signs for you. The God is Knowing and Wise.

Examining the usage

TH L TH occurs twice in this verse.

First in thalātha marrātin, then in thalāthu ʿawrātin.

The first expression counts occasions for requesting permission.

The second identifies the same three periods as situations of privacy.

This distinction matters.

Three remains constant in both expressions, but its counted noun changes: marrāt and ʿawrāt.

ʿAwrāt in this context should therefore not be translated simply as three bodily organs.

The verse concerns three times when putting aside clothing and needing privacy are more likely.

Three itself, however, does not mean privacy; that meaning comes from ʿawrāt and the verse’s context.

Nor do three specified occasions establish that no respect for personal privacy is necessary at all other times.

The verse explains its addressees’ circumstances and their ordinary movement among one another. Other verses also discuss permission to enter and household privacy.

10. Three people, three groups, and three branches: different things counted

Al-Mujādilah 58:7: The God and three people’s private conversation

Verse text

أَلَمْ تَرَ أَنَّ اللَّهَ يَعْلَمُ مَا فِي السَّمَاوَاتِ وَمَا فِي الْأَرْضِ مَا يَكُونُ مِنْ نَجْوَىٰ ثَلَاثَةٍ إِلَّا هُوَ رَابِعُهُمْ وَلَا خَمْسَةٍ إِلَّا هُوَ سَادِسُهُمْ وَلَا أَدْنَىٰ مِنْ ذَٰلِكَ وَلَا أَكْثَرَ إِلَّا هُوَ مَعَهُمْ أَيْنَ مَا كَانُوا ثُمَّ يُنَبِّئُهُمْ بِمَا عَمِلُوا يَوْمَ الْقِيَامَةِ إِنَّ اللَّهَ بِكُلِّ شَيْءٍ عَلِيمٌ

a-lam tara anna Allāha yaʿlamu mā fī al-samāwāti wa-mā fī al-arḍi mā yakūnu min najwā thalāthatin illā huwa rābiʿuhum wa-lā khamsatin illā huwa sādisuhum wa-lā adnā min dhālika wa-lā akthara illā huwa maʿahum ayna mā kānū thumma yunabbiʾuhum bi-mā ʿamilū yawma al-qiyāmati inna Allāha bi-kulli shayʾin ʿalīmun

English translation

Do you not see that The God knows whatever is in the heavens and the earth? There is no private conversation among three without Him being their fourth, nor among five without Him being their sixth, nor fewer than that or more without Him being with them wherever they are. Then, on the Day of Resurrection, He will inform them of what they did. The God indeed knows all things.

Examining the usage

Thalāthatin here counts the people taking part in a private conversation.

The following expression, “without Him being their fourth,” speaks of The God as fourth.

This fourthness should not be turned into a bodily presence of The God confined to one place while disregarding the verse’s opening and closing.

The verse begins with His knowledge of whatever is in the heavens and the earth and ends with His knowledge of everything.

The context thus connects His presence with the comprehensiveness of His knowledge and awareness.

The verse is also not limited to three people: it mentions five, fewer, and more.

Three here is therefore an example illustrating the reach of divine awareness, rather than a claim that The God is present only in three-person conversations.

Al-Wāqiʿah 56:7: three groups

Al-Wāqiʿah 56:7 states:

وَكُنْتُمْ أَزْوَاجًا ثَلَاثَةً

wa-kuntum azwājan thalāthatan

English translation

And you will be three groups.

Thalāthatan here refers to three groups.

The following verses identify them: the companions of the right, the companions of the left, and the foremost.

The count of three is explicit, while each group’s characteristics and outcome come from the following verses.

Three itself should not be taken to mean salvation, punishment, or superiority.

Al-Zumar 39:6: three darknesses

In Al-Zumar 39:6, the Qur’an speaks of human creation in ẓulumātin thalāthin, “three darknesses.”

Here three counts darknesses.

The number itself does not identify them.

Anyone matching them to three specified bodily or embryonic structures must therefore provide independent, compatible evidence.

Three alone cannot support attributing a definitive list of three membranes, tissues, or embryonic stages to the Qur’an.

The verse itself emphasizes successive human creation in mothers’ wombs and in three darknesses.

Al-Mursalāt 77:30: a shadow with three branches

Al-Mursalāt 77:30 states:

انْطَلِقُوا إِلَىٰ ظِلٍّ ذِي ثَلَاثِ شُعَبٍ

inṭaliqū ilā ẓillin dhī thalāthi shuʿabin

English translation

Go toward a shadow possessing three branches.

Thalāthi here counts branches.

The number alone cannot determine the shadow’s precise geometry or physical nature.

Nor should it be turned into three groups of people or three historical stages without evidence.

Al-Kahf 18:25: three hundred years and nine more

Verse text

وَلَبِثُوا فِي كَهْفِهِمْ ثَلَاثَ مِائَةٍ سِنِينَ وَازْدَادُوا تِسْعًا

wa-labithū fī kahfihim thalātha miʾatin sinīna wa-izdādū tisʿan

English translation

They remained in their cave for three hundred years and added nine.

Examining the usage

Thalātha miʾatin denotes three hundred: three hundreds.

Its numerical value is clear.

The next verse, Al-Kahf 18:26, nevertheless says that The God knows best how long they remained.

Contextual examination must therefore consider whether three hundred and nine years is a direct account of the actual duration or follows statements and disagreements reported by the Qur’an before referring the matter to divine knowledge.

Older readings also differ on this issue.

Al-Ṭabarī on Al-Kahf 18:25: differing readings of the reported duration

Three hundred itself cannot resolve that difference. Other numerical uses must also be considered: three thousand angels in Āl ʿImrān 3:124; the three whose case had been deferred in Al-Tawbah 9:118; thirty nights of Moses’ appointed meeting in Al-Aʿrāf 7:142; and thirty months for pregnancy and weaning together in Al-Aḥqāf 46:15. Three days of fasting also occur in Al-Baqarah 2:196 and Al-Māʾidah 5:89. Each case requires identifying what the number counts and its conditions from the verse itself.

Matching three hundred and nine years to the difference between solar and lunar years likewise requires independent calendrical and contextual examination; it is not a meaning contained in TH L TH itself.

11. Morphology and distinctions from nearby roots

Thalāthah and thalāth

In Arabic, the form of three is connected to the counted noun’s grammatical gender.

Thalāthatu rijālin refers to three men; thalāthu nisāʾin refers to three women.

The difference concerns numeral–noun construction, not quantity.

Thus thalāthatu ayyāmin and thalāthu layālin both express three, but the numeral changes because yawm and laylah have different grammatical genders.

Thalāthah and thulāth

Thalāthah names the number three.

Thulāth in mathnā wa-thulātha wa-rubāʿ expresses distribution in threes.

This distinction matters in Al-Nisāʾ 4:3 and Fāṭir 35:1.

Turning the distributive form into an arithmetic sum or a command to perform several arrangements simultaneously lacks grammatical justification.

Thālith and thuluth

Thālith is the third member of a set.

Thuluth is one-third of a whole.

Although derived from one root, they do not have identical meanings.

A family’s third child, for example, does not necessarily own one-third of its property.

Nor is someone receiving one-third of an estate necessarily the third heir in an ordering.

Ordinal position and fractional proportion must therefore remain distinct.

TH L TH compared with TH N Y (thanā)

Study of TH N Y

TH N Y includes the fields of two, second, repetition, and returning.

Mathnā and thulātha occur together in Al-Nisāʾ 4:3 and Fāṭir 35:1.

This pairing shows that the roots are related in distributive counting but remain independent.

Mathānī in Al-Ḥijr 15:87 also belongs to TH N Y, not TH L TH.

The seven mathānī should therefore not be defined simply through the root for three.

TH L TH compared with R B ʿ (rabaʿa)

Study of R B ʿ

R B ʿ also occurs in the numerical fields of four, fourth, and one-quarter.

Al-Mujādilah 58:7 places three people and The God’s being fourth in the same sentence.

This proximity does not mean that TH L TH itself means four.

Three counts the conversing people; fourth supplies another descriptive position within the same construction.

TH L TH compared with N Ṣ F (niṣf)

Study of N Ṣ F (Not yet published)

Niṣf denotes half and division into two equal parts.

Thuluth denotes one-third.

Al-Muzzammil 73:20 places half, one-third, and two-thirds together.

These fractions differ mathematically and linguistically, while applying to a single whole such as the night.

A change in the fraction’s amount should therefore not be confused with a change in the subject itself.

TH L TH compared with Q S M (qasama)

Study of Q S M (Not yet published)

Q S M concerns division and separating shares.

Thuluth is a specified proportion of a whole.

Property may be divided into three parts, but qasama itself does not necessarily mean threefold division.

The presence of thuluth in inheritance verses likewise does not require every kind of division to be into three.

TH L TH compared with TH L L (thalla)

Study of TH L L

TH L L is an independent root examined in fields including collapse, separation, and a group or company.

The Qur’anic thullah belongs to that root, not TH L TH.

Similarity between the opening letters should not lead to merging the roots into one entry.

12. Translation proposals for Forqan

In counting uses, the direct equivalent of thalāthah and thalāth is “three.”

Thalāthati ayyāmin is “three days,” thalātha layālin is “three nights,” and thalāthatu ashhurin is “three months.”

Thuluth should retain “one-third,” and thuluthān or thuluthā “two-thirds.”

Thuluthayi al-layli is “two-thirds of the night”; thuluthahu is “one-third of it.”

For thālith, “third” is appropriate according to context.

In Yā Sīn 36:14, “We reinforced them with a third” conveys the sentence’s construction.

In Al-Māʾidah 5:73, thālithu thalāthatin may be translated “the third of three” to preserve the numerical structure of the criticized claim. Its doctrinal explanation belongs in a separate reflection.

For al-thālithata in Al-Najm 53:20, “the third” is a natural equivalent.

For thulāth, “three at a time” or “in groups of three” is appropriate.

The translation of Al-Nisāʾ 4:3 should not add two, three, and four together. Nor should the same construction in Fāṭir 35:1 yield nine wings.

For thalāthata qurūʾin, the initial proposal is “three periods”; defining qurūʾ requires the study of that root.

For ẓulumātin thalāthin, “three darknesses” is appropriate. Introducing three medical or bodily structures into the main translation without explicit textual support is unwarranted.

In Al-Ḥijr 15:87, sabʿan mina al-mathānī contains seven, which belongs to another root and should not be included under this root because of a conceptual similarity with grouping.

The shared principle is that number, proportion, order, and distribution must remain distinct in translation.

13. Final synthesis

TH L TH in Arabic and the Qur’an belongs to the field of counting three and its related proportions.

Within this family, thalāthah and thalāth count three; thālith gives third position; thuluth gives one-third of a whole; thuluthān gives two-thirds; and thulāth in the distributive construction mathnā wa-thulātha wa-rubāʿ gives groups of three.

These distinctions are substantive and necessary.

The Qur’an uses three to count people, days, nights, months, waiting periods, occasions for requesting permission, groups, and various structures.

What is counted does not change the number’s meaning.

Three days of fasting, three months of waiting, and three messengers all use the quantity three; each has its own rulings and characteristics established by context.

In inheritance verses, one-third and two-thirds are exact ratios, while who receives each share depends on the verses’ conditions and legal structure.

In Al-Muzzammil 73:20, the same ratios describe the night’s duration without acquiring an economic meaning.

In Al-Nisāʾ 4:3 and Fāṭir 35:1, thulāth is distributive and must not be confused with adding numbers or imposing several arrangements simultaneously.

In Al-Nisāʾ 4:171 and Al-Māʾidah 5:73, three occurs in the critique of threefold claims about divinity. Three itself, however, does not inherently mean associating partners with The God. The criticism concerns attributing a threefold structure to His unique divinity.

In Al-Mujādilah 58:7, three people illustrate the comprehensive divine awareness of private conversation, without reducing His being fourth to bodily presence in a human gathering.

In the cave companions’ story, Al-Kahf 18:22 places three within reported statements about their number; this must be distinguished from the Qur’an’s final judgment.

Elsewhere, three can be an actual quantity, part of an image, or an element in describing an event.

Thus three is not in itself a symbol of perfection, inherently a mark of holiness, or a bearer of one hidden meaning in every use.

Final definition: TH L TH denotes three and its related forms: counting three things, third position in a set, one-third and two-thirds of a quantity, and dividing or distributing people and objects into groups of three.

Understanding each use requires identifying what the number counts, whether it expresses ordinal position or a fraction, and whether it occurs in a narrative, comparison, legal or doctrinal passage, or reported speech.

Maintaining these distinctions preserves the root’s precise lexical meaning and prevents imposing family rulings, inheritance shares, theological claims, or scientific theories upon the number three itself.
