The Qur’anic Root F Ṣ L (فَصَلَ)

1. Introduction and semantic field

The three-letter Arabic root F Ṣ L means separating one thing from another, establishing their boundary, and ending their continuity or intermixture. Separation may be physical, as when two parts separate at their connection; spatial, as when a caravan leaves its stopping place; or expressed in speech and judgment, when subjects become distinct, ambiguity recedes, and competing claims are decided.

The family includes mafṣil for a joint between bones, fiṣāl for weaning a child, faṣīlah for close relatives, faṣl for separation and judgment, and tafṣīl for explaining a subject’s components clearly and distinctly.

The root occurs 43 times in the Qur’an, in nine morphological groups. Its uses range from armies and caravans departing to weaning, divine judgment, the Last Day, and the clear exposition of divine signs.

Qur’anic morphology: 43 occurrences in nine groups

This breadth should not turn every use into one abstract meaning. Faṣalat al-ʿīr concerns a caravan departing; fiṣāl in infancy means the end of feeding on milk; yafṣilu baynahum concerns judgment; and faṣṣalnā al-āyāt concerns clearly distinguishing and explaining the signs.

These uses are semantically related, but each form’s precise meaning follows from its construction and context.

2. Semantic core and important forms

Separating and establishing a boundary

In Maqāyīs al-Lughah, Ibn Fāris defines the root’s core as follows:

الْفَاءُ وَالصَّادُ وَاللَّامُ كَلِمَةٌ صَحِيحَةٌ تَدُلُّ عَلَى تَمْيِيزِ الشَّيْءِ مِنَ الشَّيْءِ وَإِبَانَتِهِ عَنْهُ

al-fāʾu wa-al-ṣādu wa-al-lāmu kalimatun ṣaḥīḥatun tadullu ʿalā tamyīzi al-shayʾi mina al-shayʾi wa-ibānatihi ʿanhu

“Fāʾ, ṣād, and lām form a sound lexical principle indicating distinguishing one thing from another and separating it from it.”

The definition has two aspects: tamyīz means identifying a distinction, while ibānah means separating and making something distinct from another.

Physical separation may actually put distance between things. Judgment, however, need not separate people spatially; distinguishing truth from falsehood, conflicting claims, or each party’s responsibility can suffice.

Ibn Fāris also places expressions concerning judgment, a young camel separating from its mother, and the joint between bones within this family.

The core is therefore not merely cutting, but separating and distinguishing. Cutting is one way to create separation; faṣl can also occur without cutting or physical damage.

Maqāyīs al-Lughah: the core definition of F Ṣ L

Physical imagery: a joint and a string of beads

A clear image of the root can be found in the human body.

Two bones meet at a joint. It both distinguishes the two bony parts and allows them to remain connected within a continuous structure.

Arabic calls this a mafṣil.

This image shows that faṣl does not always mean completely severing a relationship. Sometimes the boundary is distinct while both parts remain within one whole.

Another image is a string of beads. Placing a bead of different material or color between others makes their division more apparent. Arabic calls such a separating bead a fāṣilah.

Within the same field, tafṣīl can mean distinguishing a subject’s parts and clarifying their boundaries.

This does not establish that every Qur’anic use of tafṣīl originated in necklace making. The image helps explain the relationship between separation and clarification; it does not prove a definitive history of semantic development.

Important lexical forms

فَصَلَ يَفْصِلُ is Form I. Depending on the construction, it means to separate, depart from a place, or judge between people or matters.

فَصْل is a verbal noun and noun concerning separation, demarcation, and decisive judgment. It appears in expressions such as faṣl al-khiṭāb and yawm al-faṣl.

فَصَّلَ يُفَصِّلُ is Form II. Its Qur’anic uses concern clearly distinguishing subjects, explaining components separately, and elucidating the signs.

تَفْصِيل is the Form II verbal noun: making a subject clear and distinct through its components, limits, or distinctions.

مُفَصَّل is the Form II passive participle, describing something whose parts or meanings have been distinctly explained.

فَاصِل is the Form I active participle, meaning one who separates or judges. Its plural al-fāṣilīn occurs in the Qur’an.

فِصَال in infancy means weaning a child and ending that stage of feeding.

فَصِيل names a young camel, particularly in connection with separation from its mother’s milk. It does not occur in the Qur’an.

فَصِيلَة denotes close relatives or a branch of a family to which someone belongs.

فَيْصَل in Arabic can mean decisive judgment, something settling a dispute between parties, or a person who judges.

مَفْصِل names the point where two bones meet and are distinct.

اِنْفَصَلَ means to separate or move apart.

فَاصِلَة names something marking a boundary or interval between two parts. It later acquired technical meanings in linguistic disciplines.

The Qur’an uses the Form I and Form II verbs, the nouns faṣl, fiṣāl, and tafṣīl, the descriptions fāṣil and mufaṣṣal, and the noun faṣīlah. Fayṣal, mafṣil as a bodily joint, and the independent form infaṣala do not occur there.

3. Older Arabic usage

Physical separation and points of connection

فَصَلْتُ الشَّيْءَ فَانْفَصَلَ means “I separated the thing, and it separated.”

The construction distinguishes the action from its result. Faṣaltu is transitive and acts on something; infaṣala describes that thing becoming separate.

Bodily joints mark where bones are distinct. In descriptions of land, mafṣil can also mean an interval or passage between two mountains.

Here, faṣl does not mean destroying one of the parts. Both mountains remain, with a distinct interval or passage between them.

Dictionaries cite a verse by Abū Dhuʾayb al-Hudhalī concerning clear water like that of these mountain passages. He lived across the pre-Islamic and Islamic periods; without dating its composition, the verse should not be called securely pre-Qur’anic.

These uses establish boundaries and separation in descriptive Arabic. They do not, by themselves, prove that these senses historically preceded uses concerning judgment or explanation.

Lisān al-ʿArab and Tāj al-ʿArūs: joints, weaning, and semantic branches

Faṣl in judgment: a pre-Islamic poetic witness

A poem by the pre-Islamic poet Zuhayr ibn Abī Sulmā describes a group’s ability to settle disputes and difficult matters:

هُمُ جَرَّدُوا أَحْكَامَ كُلِّ مُضِلَّةٍ
مِنَ الْعُقْمِ لَا يُلْفَى لِأَمْثَالِهَا فَصْلُ

humu jarradū aḥkāma kulli muḍillatin / mina al-ʿuqmi lā yulfā li-amthālihā faṣlu

“They made clear the judgments of perplexing, intractable matters, for whose like no resolution is readily found.”

Faṣl here is not physical parting. It concerns a difficult matter whose settlement and judgment are not readily achieved.

Muḍillah in this context names a complicated, bewildering matter. Faṣl concerns resolution and an end to uncertainty.

The witness shows that faṣl as judgment and settling disputes is not merely an invention of later Qur’anic commentaries; it also appears in poetry attributed to the pre-Islamic period. The line is transmitted among Zuhayr’s poems, although wording and textual transmission should, as with other old poetry, remain distinct from the lexical sense.

Transmitted text of Zuhayr’s poem: faṣl in judgment

Fiṣāl: ending a child’s nursing stage

Fiṣāl is one physical and social application of the root.

Arabic uses faṣala and fiṣāl when a child’s feeding on the mother’s milk ends.

This does not sever the relationship between mother and child. After weaning, the child remains hers and may continue living in her arms and care.

What ends is the particular relationship of feeding on milk.

The more precise meaning here is therefore weaning or ending the nursing stage, rather than separating the child completely from the mother.

Faṣīl as the name of a young camel belongs to the same field: a young animal reaching the stage of separation from its mother’s milk, or identified in relation to it.

This shows that faṣl can end a particular condition without eliminating all bonds between the parties.

Faṣīlah: a branch of the family

In Arabic social and tribal usage, faṣīlah names a section of the family or close relatives.

A larger group is distinguished into branches, each with a particular relationship to its members.

Faṣīlah should not mean any arbitrary group of people. Its genealogical use concerns kinship.

Nor should it be confused with fiṣāl, weaning. Their shared root and some similar letters do not make the nouns identical.

Tafṣīl: distinguishing components to clarify meaning

فَصَّلَ الْكَلَامَ means explaining speech clearly and distinctly, allowing the subject’s components to be recognized and ambiguity reduced.

This use is related to physical separation without being identical to it.

Explaining a complex subject’s components and boundaries precisely lets the listener distinguish what was previously confused or unclear.

Tafṣīl can therefore concern both differentiation into parts and clarification of meaning.

This does not mean that every distinctly explained statement must be long. A short statement may clarify the essential boundaries sufficiently for its subject.

Conversely, length alone does not establish good exposition. A very long explanation may still confuse its subjects.

This matters for Qur’anic tafṣīl: explaining signs distinctly does not merely mean increasing the number of words.

4. Qur’anic uses

A. فَصَلَ: departing and setting out

The first field of Qur’anic usage is leaving a place and beginning to move.

In Al-Baqarah 2:249, فَلَمَّا فَصَلَ طَالُوتُ بِالْجُنُودِ describes Saul setting out with his troops.

Here, faṣala does not mean dividing the army into parts. Saul travels with the army and leaves the previous position.

The bāʾ in bi-al-junūd expresses the troops accompanying Saul. A natural rendering is therefore “when Saul set out with the troops.”

The same use appears in Joseph’s story:

وَلَمَّا فَصَلَتِ الْعِيرُ قَالَ أَبُوهُمْ إِنِّي لَأَجِدُ رِيحَ يُوسُفَ ۖ لَوْلَا أَنْ تُفَنِّدُونِ

Wa-lammā faṣalati l-ʿīru qāla abūhum innī la-ajidu rīḥa Yūsufa lawlā an tufannidūn.

“When the caravan departed, their father said: I indeed perceive Joseph’s scent, if you will not consider me foolish.”

Yūsuf 12:94

Faṣalat al-ʿīr describes the caravan setting out and leaving its former location.

The verb is intransitive and al-ʿīr its subject. It does not mean that the caravan divided into several groups.

These occurrences show that faṣl can mean ending one’s presence at a place and departing. Spatial separation here concerns the start of movement, rather than stopping or standing still.

B. فِصَال: the end of nursing

The Qur’an mentions fiṣāl concerning children three times.

Luqmān says:

وَوَصَّيْنَا الْإِنْسَانَ بِوَالِدَيْهِ حَمَلَتْهُ أُمُّهُ وَهْنًا عَلَىٰ وَهْنٍ وَفِصَالُهُ فِي عَامَيْنِ أَنِ اشْكُرْ لِي وَلِوَالِدَيْكَ إِلَيَّ الْمَصِيرُ

wa-waṣṣaynā al-insāna bi-wālidayhi ḥamalat-hu ummuhu wahnan ʿalā wahnin wa-fiṣāluhu fī ʿāmayni ani ushkur lī wa-li-wālidayka ilayya al-maṣīru

“We enjoined the human being concerning his parents. His mother carried him in weakness upon weakness, and his weaning is in two years. Give thanks to Me and to your parents; to Me is the return.”

Luqmān 31:14

Fiṣāluhu here refers to the end of the child’s nursing stage.

Al-Aḥqāf 46:15 also places ḥamluhu wa-fiṣāluhu together, stating a combined period of thirty months for carrying and weaning.

After describing mothers nursing and the associated responsibilities, Al-Baqarah 2:233 states that if the parents wish to wean through mutual consent and consultation, there is no blame upon them.

This helps explain fiṣāl by placing it within an actual family decision.

It means ending nursing, rather than separating the child from the mother by severing their family or emotional relationship.

Consent and consultation come from separate expressions in the verse; they are not components of fiṣāl’s lexical meaning.

All three uses concern ending a particular feeding relationship. After fiṣāl, the child remains the parents’ child.

Fiṣāl clearly illustrates ending a particular condition without removing all bonds between two parties.

C. فَصِيلَة: close relatives

Al-Maʿārij says:

وَفَصِيلَتِهِ الَّتِي تُؤْوِيهِ

wa-faṣīlatihi allatī tuʾwīhi

“And his close relatives who shelter him.”

Al-Maʿārij 70:13

The preceding verses describe someone wishing to sacrifice his loved ones to save himself from punishment.

Faṣīlatihi here means the close relatives to whom he belongs.

Allatī tuʾwīhi describes this group: they have provided shelter and support for him.

Faṣīlah here means neither weaning nor a religious group or intellectual sect.

In tribal society, a large family may contain closer branches of kinship. Faṣīlah identifies such a group, distinguishable from the larger whole.

Its relation to a distinct family branch can be explained semantically, without claiming that the word necessarily arose from one particular historical tribal classification.

“Close relatives” or “immediate clan” is more precise than the generic “group.”

D. يَفْصِلُ بَيْنَهُمْ: judgment and settling disagreement

Several verses use the Form I verb directly for judging between people or groups.

Al-Sajdah says:

إِنَّ رَبَّكَ هُوَ يَفْصِلُ بَيْنَهُمْ يَوْمَ الْقِيَامَةِ فِيمَا كَانُوا فِيهِ يَخْتَلِفُونَ

Inna rabbaka huwa yafṣilu baynahum yawma al-qiyāmati fīmā kānū fīhi yakhtalifūn

“Indeed, your Lord Himself will judge between them on the Day of Resurrection concerning that in which they differed.”

Al-Sajdah 32:25

The subject of faṣl here is disagreement between people.

Baynahum identifies the parties to the judgment, and fī-mā kānū fīhi yakhtalifūna identifies the disputed matter.

Faṣl therefore means determining the dispute’s outcome and judging between them, rather than physically separating people.

After naming different religious groups, Al-Ḥajj 22:17 also states that The God will judge between them on the Day of Resurrection.

Al-Mumtaḥanah 60:3 likewise speaks of divine judgment between people on that day.

These uses show that faṣl in judgment is more than stating a difference between claims; it can mean determining the outcome and ending uncertainty.

The verb alone does not establish a judgment’s value. Human judgment may be just or unjust. When the Qur’an attributes faṣl to The God, its justice and truth follow from divine attributes and acts and the verses’ context.

خَيْرُ الْفَاصِلِينَ: the best of judges

Al-Anʿām says:

قُلْ إِنِّي عَلَىٰ بَيِّنَةٍ مِنْ رَبِّي وَكَذَّبْتُمْ بِهِ ۚ مَا عِنْدِي مَا تَسْتَعْجِلُونَ بِهِ ۚ إِنِ الْحُكْمُ إِلَّا لِلَّهِ ۖ يَقُصُّ الْحَقَّ ۖ وَهُوَ خَيْرُ الْفَاصِلِينَ

qul innī ʿalā bayyinatin min rabbī wa-kadhdhabtum bihi mā ʿindī mā tastaʿjilūna bihi ini al-ḥukmu illā li-Allāhi yaquṣṣu al-ḥaqqa wa-huwa khayru al-fāṣilīna

“Say: I stand upon clear evidence from my Lord, and you have denied it. What you seek to hasten is not in my keeping. Judgment belongs only to The God; He declares the truth, and He is the best of judges.”

Al-Anʿām 6:57

Al-fāṣilīn is the plural active participle of fāṣil.

Here, faṣl accompanies judgment and truth. The Prophet declares that what the opponents seek to hasten is not in his control and that judgment belongs to The God.

Khayr al-fāṣilīn therefore refers here to the best of those who judge.

It should not be rendered “the best of separators” in a physical sense, since judgment and determining the truth are at issue.

Nor does the expression mean that people can never judge between disputants. Other Qur’anic verses speak of just human judgment.

The principal distinction is that divine judgment relates to The God’s knowledge and justice, independently of human cognitive limitations and personal interests.

E. يَوْمُ الْفَصْلِ: the day of decisive judgment

Yawm al-faṣl is a prominent nominal expression of this root.

Al-Nabaʾ says:

إِنَّ يَوْمَ الْفَصْلِ كَانَ مِيقَاتًا

inna yawma al-faṣli kāna mīqātan

“Indeed, the Day of Judgment is an appointed time.”

Al-Nabaʾ 78:17

Faṣl here concerns judgment and determining outcomes; mīqāt emphasizes an appointed time.

Al-Dukhān also says:

إِنَّ يَوْمَ الْفَصْلِ مِيقَاتُهُمْ أَجْمَعِينَ

inna yawma al-faṣli mīqātuhum ajmaʿīna

“Indeed, the Day of Judgment is their appointed time, all together.”

Al-Dukhān 44:40

Al-Mursalāt 77:13, Al-Mursalāt 77:14, and Al-Mursalāt 77:38 repeat the expression.

Al-Ṣāffāt 37:21 also tells those who denied that this is the very Day of Judgment they rejected.

These uses name the day when deeds and disagreements are judged and their results determined.

Resurrection also involves people’s different outcomes. Nevertheless, faṣl here should not be restricted to their spatial separation.

“Day of Judgment” is concise and natural. “Day of resolution” also evokes decisive settlement, but the former is more familiar and fluent in Persian.

F. فَصْلَ الْخِطَابِ: clear speech and decisive judgment

Ṣād says concerning David:

وَشَدَدْنَا مُلْكَهُ وَآتَيْنَاهُ الْحِكْمَةَ وَفَصْلَ الْخِطَابِ

wa-shadadnā mulkahu wa-ātaynāhu al-ḥikmata wa-faṣla al-khiṭābi

“We strengthened his rule and gave him wisdom and decisive, clear speech.”

Ṣād 38:20

Faṣl al-khiṭāb appears alongside wisdom.

Khiṭāb concerns speech and addressing others. Faṣl can indicate the ability to clarify boundaries, speak decisively, and end ambiguity or disagreement.

Classical explanations include several readings: clear, decisive speech; sound judgment between people; and particular rhetorical formulas.

The first two have clearer lexical and contextual support. David is presented as possessing wisdom and the capacity for speech and judgment.

Ṣād 38:21, Ṣād 38:22, Ṣād 38:23, Ṣād 38:24, Ṣād 38:25, and Ṣād 38:26 then recount two disputants approaching David and the issue of judgment between them. This strengthens the connection with judgment.

It does not follow that faṣl al-khiṭāb names only a particular ceremonial formula for beginning or ending a speech. Such a restriction needs independent evidence.

“Decisive, clear speech” or “the ability to judge and speak decisively” is suitable, although the latter brings some contextual explanation into the translation.

G. كَلِمَةُ الْفَصْلِ: a decisive decree and the question of respite

Al-Shūrā says:

أَمْ لَهُمْ شُرَكَاءُ شَرَعُوا لَهُمْ مِنَ الدِّينِ مَا لَمْ يَأْذَنْ بِهِ اللَّهُ ۚ وَلَوْلَا كَلِمَةُ الْفَصْلِ لَقُضِيَ بَيْنَهُمْ ۗ وَإِنَّ الظَّالِمِينَ لَهُمْ عَذَابٌ أَلِيمٌ

am lahum shurakāʾu sharaʿū lahum mina al-dīni mā lam yaʾdhan bihi allāhu wa-lawlā kalimatu al-faṣli la-quḍiya baynahum wa-inna al-ẓālimīna lahum ʿadhābun alīmun

“Or do they have partners who have prescribed for them a religion that The God has not permitted? Had it not been for the decisive decree, judgment would have been passed between them. Indeed, the wrongdoers will have a painful punishment.”

Al-Shūrā 42:21

Kalimat al-faṣl concerns a decisive decree or ruling in relation to the timing of divine judgment.

The construction wa-lawlā ... la-quḍiya baynahum indicates that without this decree, judgment would have occurred in that situation.

The expression therefore cannot simply mean a statement whose components have been well explained. Judgment and the time of resolution form the context.

Nor should the decree be equated with the act of judgment itself, since the verse places it in a conditional relationship with la-quḍiya baynahum.

The verse also raises a separate issue of religious legislation: partners prescribing religion without The God’s permission. That criticism comes from the verse’s opening, rather than F Ṣ L alone.

“Decisive decree” or “determining ruling” can therefore explain the expression, while its full relationship to divine respite requires other contextual verses as well.

H. قَوْلٌ فَصْلٌ: decisive and distinguishing speech

Al-Ṭāriq says:

إِنَّهُ لَقَوْلٌ فَصْلٌ

innahu la-qawlun faṣlun

“Indeed, it is a decisive, distinguishing word.”

Al-Ṭāriq 86:13

The next verse says:

وَمَا هُوَ بِالْهَزْلِ

wa-mā huwa bi-al-hazli

“And it is no idle jest.”

Al-Ṭāriq 86:14

Faṣl here describes qawl, speech.

Its juxtaposition with the negation of hazl shows that the statement is serious and decisive, rather than playful entertainment.

Semantically, qawl faṣl can be speech that clarifies reality and distinguishes truth from falsehood.

Classical sources also explain qawl faṣl as true speech, so this gloss should not be dismissed as unsupported. Nevertheless, faṣl is not synonymous with truth or truthfulness in every use; the determining and distinguishing quality also matters in this expression.

Tāj al-ʿArūs: qawl faṣl explained as true or decisive speech

This distinction matters in translation. Rendering it only “true speech” leaves part of the separating and decisive sense unexpressed.

5. Explaining the signs: from distinguishing meaning to clarifying the Book

Most Qur’anic uses of F Ṣ L belong to the field of tafṣīl.

Here, faṣl concerns clear exposition, distinguishing components, and establishing a subject’s boundaries, rather than spatial departure or weaning.

فَصَّلْنَا الْآيَاتِ: making the signs clear

Al-Anʿām says:

وَكَذَٰلِكَ نُفَصِّلُ الْآيَاتِ وَلِتَسْتَبِينَ سَبِيلُ الْمُجْرِمِينَ

wa-kadhālika nufaṣṣilu al-āyāti wa-li-tastabīna sabīlu al-mujrimīna

“Thus We explain the signs distinctly, so that the way of the guilty may become clear.”

Al-Anʿām 6:55

Nufaṣṣilu is the Form II imperfect verb, with al-āyāt as its object.

The continuation wa-li-tastabīna sabīlu al-mujrimīn identifies one result: the guilty people’s way becomes clear and recognizable.

This shows that tafṣīl can concern making distinctions between paths, conduct, and standards clear.

Nufaṣṣilu does not simply mean “We separate.” Distinguishing here enables clarity of meaning and understanding of the signs.

The same construction appears in Al-Anʿām 6:97, Al-Anʿām 6:98, and Al-Anʿām 6:126, associating explanation of the signs with knowledge, understanding, and remembrance.

Al-Aʿrāf 7:32, Al-Aʿrāf 7:174, Al-Tawbah 9:11, Yūnus 10:5, Yūnus 10:24, Al-Raʿd 13:2, and Al-Rūm 30:28 also associate it with purposes such as knowing, reflecting, reasoning, or returning.

This repetition shows that tafṣīl is more than a text’s visible formatting. Making signs clear and distinct concerns the audience’s ability to understand and benefit.

Knowledge, reasoning, and remembrance nevertheless come from other verbs and expressions in the verses. They should not all become components of faṣṣala’s lexical meaning.

أُحْكِمَتْ آيَاتُهُ ثُمَّ فُصِّلَتْ

The opening of Hūd says:

الر ۚ كِتَابٌ أُحْكِمَتْ آيَاتُهُ ثُمَّ فُصِّلَتْ مِنْ لَدُنْ حَكِيمٍ خَبِيرٍ

alif lām rā, kitābun uḥkimat āyātuhu thumma fuṣṣilat min ladun ḥakīmin khabīrin

“Alif, lām, rā. A Book whose signs have been made firm, then distinctly explained, from One wise and fully aware.”

Hūd 11:1

There are two passive verbs: uḥkimat from Ḥ K M and fuṣṣilat from F Ṣ L.

Their lexical meanings differ.

Iḥkām concerns firmness, coherence, and preventing weakness or disorder. Tafṣīl concerns making components and meanings clear and distinct.

Thumma stands between the verbs. It can indicate sequence, but alone does not prove that the Qur’an was produced in two separate chronological stages or that the signs initially existed entirely without exposition.

Together, the descriptions can express a Book that is firm and coherent while its signs are clearly and distinctly explained.

Fuṣṣilat 41:3 also says:

كِتَابٌ فُصِّلَتْ آيَاتُهُ قُرْآنًا عَرَبِيًّا لِقَوْمٍ يَعْلَمُونَ

kitābun fuṣṣilat āyātuhu qurʾānan ʿarabiyyan li-qawmin yaʿlamūna

“A Book whose signs have been distinctly explained: an Arabic Qur’an for people who know.”

Fuṣṣilat 41:3

Here, explanation of the signs accompanies the Qur’an’s Arabic language and an audience who knows.

This shows the importance of clear expression and language understandable to the audience.

Fuṣṣilat 41:44 also presents hypothetical opponents asking about explanation of the signs if the Qur’an were non-Arabic. Understanding and language are therefore relevant to tafṣīl.

Tafṣīl should not, however, be restricted to being Arabic. Arabic is one characteristic of the Book here; tafṣīl concerns how its signs are expressed and clarified.

الْكِتَابَ مُفَصَّلًا: the distinctly explained Book

Al-Anʿām says:

أَفَغَيْرَ اللَّهِ أَبْتَغِي حَكَمًا وَهُوَ الَّذِي أَنْزَلَ إِلَيْكُمُ الْكِتَابَ مُفَصَّلًا ۚ وَالَّذِينَ آتَيْنَاهُمُ الْكِتَابَ يَعْلَمُونَ أَنَّهُ مُنَزَّلٌ مِنْ رَبِّكَ بِالْحَقِّ ۖ فَلَا تَكُونَنَّ مِنَ الْمُمْتَرِينَ

a-fa-ghayra allāhi abtaghī ḥakaman wa-huwa al-ladhī anzala ilaykumu al-kitāba mufaṣṣalan wa-al-ladhīna ātaynāhumu al-kitāba yaʿlamūna annahu munazzalun min rabbika bi-al-ḥaqqi fa-lā takūnanna mina al-mumtarīna

“Shall I seek a judge other than The God, when He is the One who has sent down to you the Book distinctly explained? Those to whom We gave the Book know that it has been sent down in truth from your Lord. So do not be among those who doubt.”

Al-Anʿām 6:114

Mufaṣṣalan is the Form II passive participle, describing the Book.

The construction matters: asking whether to seek a judge other than The God accompanies the revelation of the distinctly explained Book.

This establishes a clear relationship between the authority for judgment and the divine Book.

Verse 115 then speaks of the Lord’s word being fulfilled in truth and justice. The Book’s exposition therefore appears within a context of truth, justice, and authority in judgment.

Mufaṣṣal alone nevertheless does not mean every legal, scientific, and social ruling for all times. Its basic sense is distinct exposition and clarity of expression.

Conversely, the description should not be weakened as though the Qur’an presented itself as obscure concerning guidance and judgment and dependent on others’ independent legislation.

Its scope should be examined alongside verses concerning judgment, legislation, permitted and forbidden matters, and the sufficiency of divine exposition.

Explaining what is permitted and forbidden

An important use appears in Al-Anʿām 6:119:

وَمَا لَكُمْ أَلَّا تَأْكُلُوا مِمَّا ذُكِرَ اسْمُ اللَّهِ عَلَيْهِ وَقَدْ فَصَّلَ لَكُمْ مَا حَرَّمَ عَلَيْكُمْ إِلَّا مَا اضْطُرِرْتُمْ إِلَيْهِ ۗ وَإِنَّ كَثِيرًا لَيُضِلُّونَ بِأَهْوَائِهِمْ بِغَيْرِ عِلْمٍ ۗ إِنَّ رَبَّكَ هُوَ أَعْلَمُ بِالْمُعْتَدِينَ

wa-mā lakum allā taʾkulū mimmā dhukira ismu allāhi ʿalayhi wa-qad faṣṣala lakum mā ḥarrama ʿalaykum illā mā uḍṭurirtum ilayhi wa-inna kathīran la-yuḍillūna bi-ahwāʾihim bi-ghayri ʿilmin inna rabbaka huwa aʿlamu bi-al-muʿtadīna

“What is the matter with you that you do not eat of that over which The God’s name has been mentioned, when He has clearly explained to you what He has forbidden, except what necessity compels you to? Many mislead others through their desires without knowledge. Indeed, your Lord knows best those who transgress.”

Al-Anʿām 6:119

Faṣṣala lakum mā ḥarrama ʿalaykum concerns what The God has forbidden.

The object of exposition is specified: the things He has prohibited.

This shows that tafṣīl in religious rulings can concern clarifying the boundaries of prohibitions.

The verb alone should not carry the entire argument about permitted and forbidden matters. The prohibitions’ content, exceptions of necessity, and legislative authority follow from the relevant verses together.

The verse matters because The God attributes explaining His prohibitions to Himself, then discusses misleading people through desires and without knowledge.

Tafṣīl here therefore concerns the boundaries of divine rulings, beyond literary explanation alone.

The verb’s object matters. Exposition of signs in creation, rulings, or a historical subject may differ in manner, while all belong to making something clear and distinct.

تَفْصِيلَ كُلِّ شَيْءٍ: the scope of “everything”

After describing the lessons in narratives, Yūsuf 12:111 speaks of confirming what is before the Book and tafṣīla kulli shayʾ.

Yūnus 10:37 also contains tafṣīla al-kitāb.

Al-Anʿām 6:154 and Al-Aʿrāf 7:145 use tafṣīlan li-kulli shayʾ concerning Moses’ Book.

Al-Isrāʾ 17:12, after mentioning night and day, knowing the number of years, and reckoning, says wa-kulla shayʾin faṣṣalnāhu tafṣīlan.

These uses require examination in their own contexts.

Kull indicates comprehensiveness, but its domain depends on the sentence’s subject. “Everything” can include all components of a particular field without necessarily discussing every phenomenon in existence.

For example, a book explaining all necessary matters within a particular subject need not thereby contain detailed accounts of every technical and empirical human science.

Conversely, the comprehensiveness of kull shayʾ should not be restricted without evidence in a way that excludes essential aspects of the Qur’an’s intended guidance and judgment.

The proper question is: in relation to which subject and purpose is “everything” stated?

Context, the verb’s object, and the verses together should supply the answer, rather than an assumption that the Book must either be an encyclopedia of all sciences or merely incomplete religious hints.

آيَاتٍ مُفَصَّلَاتٍ: distinct, separately identifiable signs

Al-Aʿrāf says:

فَأَرْسَلْنَا عَلَيْهِمُ الطُّوفَانَ وَالْجَرَادَ وَالْقُمَّلَ وَالضَّفَادِعَ وَالدَّمَ آيَاتٍ مُفَصَّلَاتٍ فَاسْتَكْبَرُوا وَكَانُوا قَوْمًا مُجْرِمِينَ

fa-arsalnā ʿalayhimu al-ṭūfāna wa-l-jarāda wa-l-qummala wa-l-ḍafādiʿa wa-l-dama āyātin mufaṣṣalātin fa-stakbarū wa-kānū qawman mujrimīna

“We sent upon them the flood, locusts, lice, frogs, and blood as distinct signs; yet they acted arrogantly and were a guilty people.”

Al-Aʿrāf 7:133

Mufaṣṣalāt describes āyāt.

Unlike uses concerning exposition of the Book, this concerns events and signs sent upon Pharaoh’s people.

Mufaṣṣalāt can therefore express the signs’ distinct, separately identifiable character. Each has its own nature without being confused with the others.

Some classical explanations also connect it with signs occurring on separate occasions. That fits the field of tafṣīl, but the form alone specifies no precise interval between events.

Rendering mufaṣṣalāt merely “clear and evident” should not obscure their distinct, identifiable character.

Tafṣīl is therefore not restricted to spoken or written explanation; describing actual signs, it can indicate their distinctness and differentiation.

6. Distinctions from related roots

F Ṣ L (فَصْل) and F R Q (فَرْق)

Study of F R Q

Faṣl and farq are closely related in separation and distinction.

Farq can mean separating things, distinguishing them, or their differences becoming apparent.

Faṣl also concerns separation, but uses concerning judgment and speech emphasize establishing boundaries and ending uncertainty.

This tendency should not become an absolute rule that farq always means only recognizing differences and faṣl only final judgment.

The Qur’an uses both for separation and clarifying distinctions; their fields overlap in some contexts.

Forqan’s F R Q study also discusses this proximity. Each occurrence of F Ṣ L therefore needs its particular contribution examined, rather than an artificial, permanent distinction from farq.

F Ṣ L (فَصْل) and Q Ṭ ʿ (قَطْع)

Study of Q Ṭ ʿ

Qaṭʿ concerns cutting and breaking continuity.

In physical use, cutting can separate one part completely from another.

Faṣl can also create actual separation, but is not limited to cutting or destroying a material connection.

Weaning ends feeding on milk without severing the family relationship.

Judicial faṣl settles a dispute without requiring the parties to be physically or socially cut off from one another.

In some uses, faṣl therefore has a broader field than material cutting.

F Ṣ L (فَصْل) and Ḥ K M (حُكْم)

Study of Ḥ K M

Ḥukm concerns judgment, command, determining a matter, and preventing disorder.

Judicial faṣl concerns distinguishing claims and ending disagreement.

Both can occur within one act: a judge issues a ruling settling a dispute, involving both ḥukm and faṣl.

Not every use of ḥukm belongs to faṣl, and not every faṣl is legal judgment.

Faṣalat al-ʿīr concerns a caravan departing, and fiṣāl concerns weaning. Judgment is not intended there.

F Ṣ L (فَصْل) and Q Ḍ Y (قَضَى)

Study of Q Ḍ Y

Qaḍāʾ in Arabic concerns doing, completing, determining, and judging.

Qur’anic qaḍā can describe a matter ending, executing a command, or judgment.

Faṣl likewise concerns determining a dispute’s outcome and ending uncertainty.

Al-Shūrā 42:21 places kalimat al-faṣl and la-quḍiya baynahum together, showing related subjects expressed through different words.

The former names a determining decree or ruling; the latter states judgment taking place.

Their order does not prove an absolute theory that every faṣl precedes qaḍāʾ or every qaḍāʾ follows faṣl.

F Ṣ L (تَفْصِيل) and B Y N (بَيَان)

Study of B Y N

Bayān concerns making meaning clear and evident.

Tafṣīl can likewise clarify a subject, while retaining the image of distinguishing its components and boundaries.

A brief statement can clearly express a truth without explaining its components separately.

Tafṣīl, by contrast, may distinguish parts, conditions, and differences.

The concepts are nevertheless related: tafṣīl can itself be a method of bayān.

“Made clear” therefore suits faṣṣala in many verses. Where distinct components and limits matter, “explained distinctly” or “clarified its components” may be more suitable.

F Ṣ L (فَصْل) and Ṣ D ʿ (صَدْع)

Study of Ṣ D ʿ

Ṣ D ʿ concerns splitting and a break appearing in something.

Faṣl likewise concerns separation, but its image need not involve a fissure.

In Ṣ D ʿ, cracking stone or splitting earth can supply the central image.

In F Ṣ L, things can become separate or distinct without either developing a crack.

In speech, ṣadʿ can mean openly and plainly declaring, whereas faṣl more often concerns clearly distinguishing meanings and decisive judgment.

This is a tendency requiring assessment against the evidence of each sentence.

7. Morphological and grammatical points

The Form I verb occurs five times in the Qur’an.

In Al-Baqarah 2:249 and Yūsuf 12:94, it is intransitive, concerning departure from a place.

In Al-Ḥajj 22:17, Al-Sajdah 32:25, and Al-Mumtaḥanah 60:3, it appears in constructions concerning judgment between people.

Construction and accompanying expressions therefore matter in determining meaning.

Form II faṣṣala occurs seventeen times, prominently for clearly explaining the signs and Book.

Form II alone nevertheless does not establish division into numerous parts or a necessarily lengthy explanation. The object and context determine how exposition occurs.

Tafṣīl is the Form II verbal noun. It appears both in genitive constructions such as tafṣīla al-kitāb and emphatically with its verb, as in faṣṣalnāhu tafṣīlan.

In the latter, the verbal noun emphasizes the act of exposition without specifying its length or volume.

Mufaṣṣalan in Al-Anʿām 6:114 is a masculine singular passive participle referring to the Book.

Mufaṣṣalāt in Al-Aʿrāf 7:133 is a feminine plural description associated with āyāt. Their shared morphology does not make their referents identical: one concerns the Book, the other sent signs.

Faṣīlah and fiṣāl are also distinct nouns despite their shared root. The former concerns close relatives, the latter nursing.

In qawl faṣl, faṣl describes qawl and expresses the speech’s decisiveness.

In yawm al-faṣl, the same nominal form appears in an expression naming the Day of Judgment.

Precise forms and grammatical roles therefore prevent meanings from being confused.

8. Challenges in understanding and translation

Does tafṣīl mean stating every possible detail?

Not necessarily.

Tafṣīl concerns clear, distinct exposition, but its amount and scope depend on the subject.

Sometimes several rulings or conditions must be distinguished; elsewhere, a subject’s components require clear explanation.

When the Qur’an distinctly explains something, that subject and its context require examination.

Conversely, tafṣīl cannot without evidence be reduced to an obscure, insufficient explanation. Qur’anic uses associate it with knowledge, understanding, reasoning, and clear paths.

It should therefore imply neither that the Qur’an contains all empirical and technical sciences nor that its clarity concerning guidance and judgment is without consequence.

Does faṣl always mean completely severing a relationship?

No.

Weaning ends feeding on milk, rather than motherhood and childhood.

A joint marks a boundary between bones while they remain in a common structure.

Judgment can end a dispute while preserving the parties’ social relationship.

Complete severance is only one possible condition of separation, rather than an invariable definition.

Is every judgment faṣl?

Judgment and faṣl are often close, but not every use concerning judgment must employ faṣala.

Ḥukm and qaḍāʾ have independent fields in Arabic.

Faṣl in judgment emphasizes determining the outcome and ending uncertainty.

The word alone does not prove a judge’s justice or a ruling’s correctness. Those require independent evidence and context.

Does tafṣīl mean dividing a text into book chapters?

The Persian word faṣl for a chapter belongs to this lexical family.

This familiar writing term should not be transferred to every Qur’anic use of faṣṣala.

Saying the signs have been distinctly explained does not necessarily mean a text divided into chapters and headings like modern books.

Tafṣīl can clarify meanings, rulings, signs, and their distinctions.

Visible textual division is only one possible means of doing so.

9. Translation proposals for Forqan

For physical Form I faṣala, “separated” or “set apart” is appropriate.

For departure, as in Yūsuf 12:94, “departed” or “set out from the previous location” is more natural.

For judgment, as in Al-Sajdah 32:25, “judges” or “settles between them” is suitable.

Judicial faṣl can be rendered “resolution,” “decisive judgment,” or “determination.”

For faṣṣala concerning the Book and signs, the principal equivalents are “explained clearly,” “set out distinctly,” and “clarified its components,” depending on the sentence.

For tafṣīl, “clear, distinct exposition” or “clarifying components and boundaries” is suitable.

For mufaṣṣal, “distinctly explained” or “clearly set forth” is appropriate.

For fiṣāl concerning a child, the principal equivalent is “weaning.”

For faṣīlah, “close relatives” or “immediate clan” is suitable.

For al-fāṣilīn in Al-Anʿām 6:57, “judges” is more natural than “separators.”

The important Qur’anic expressions suggest these renderings:

• فَصْلَ الْخِطَابِ: “decisive, clear speech”
• يَوْمُ الْفَصْلِ: “the Day of Judgment”
• كَلِمَةُ الْفَصْلِ: “a decisive decree” or “a determining ruling”
• قَوْلٌ فَصْلٌ: “decisive, distinguishing speech”
• تَفْصِيلَ الْكِتَابِ: “exposition of the Book” or “clear explanation of its components”
• آيَاتٍ مُفَصَّلَاتٍ: “distinct, separately identifiable signs”

The base translation need not fit every root image into each equivalent. It should remain natural and precise, leaving lexical relationships to the study or verse reflection.

10. Conclusion

F Ṣ L in Arabic concerns separating things and making their boundaries distinct. Its field includes departing from a place, ending nursing, identifying branches of kinship, judging between people, and clearly explaining the components of speech.

Two fields are prominent in the Qur’an: judgment and settlement, and exposition and clarification of the signs. Caravan departure, weaning, and close kinship nevertheless remain actual, important uses and should not be overshadowed by religious and judicial ones.

In judgment, faṣl determines the outcome and ends disagreement. In explaining the Book, tafṣīl clarifies meanings and boundaries. Physical separation may be actual and perceptible without always severing every relationship or destroying continuity.

Faṣl should therefore not mean only cutting, judging, or explaining. Each is one use within a particular construction.

The brief meaning of F Ṣ L is: separating and distinguishing one thing from another so that its boundary, difference, or outcome becomes clear.

Qur’anic uses apply this to movement and departure, ending a stage, decisive judgment, or clear, distinct exposition. Preserving these differences is essential: lexical relationships between derivatives should not replace each verse’s actual meaning.
