The Qur’anic Root ʾ KH W

1. Introducing the root and its Qur’anic forms

The Arabic root أ خ و is recognized through brother, sister, and the relationship between them. أَخ (akh) means brother and أُخْت (ukht) sister. In its familial meaning, this relationship can arise through two shared parents, one shared parent, or milk kinship.

The family’s Arabic uses are not confined to descent, however. Someone can be another’s brother in religion, friendship, peoplehood, cooperation, or way of life. Two groups or phenomena sharing a characteristic may likewise be described as one another’s brother or sister.

The Qur’an clearly exhibits this range. Mūsā and Hārūn are brothers by family, as are Yūsuf and his brothers. Prophets such as Hūd and Ṣāliḥ are called their people’s “brother,” although many of those people rejected their invitation. Believers are described as إِخْوَة (ikhwah), whereas those who squander their resources are called إِخْوَانَ الشَّيَاطِينِ (ikhwāna al-shayāṭīn), brothers of the devils.

Qur’anic “brotherhood” therefore does not always mean having the same parents. Nor does it in itself establish faith, affection, or good conduct. Context identifies the kind of relationship and its value.

Qur’anic forms

The root أ خ و occurs 96 times in 80 verses across 31 sūrahs.

In this count, ikhwān is a plural form of akh, not a separate root.

Arabic recognizes other forms, including أُخُوَّة (ukhuwwah), brotherhood; إِخَاء (ikhāʾ), a fraternal bond; آخَى (ākhā), he established brotherhood; تَآخَى (taʾākhā), they became brothers or affiliated with one another; and مُؤَاخَاة (muʾākhāh), establishing a bond of brotherhood. These forms do not themselves occur in the Qur’an.

The root has no independent verbal occurrence in the Qur’an. All 96 instances belong to the nouns for brother and sister.

2. Brotherhood in early Arabic and morphological distinctions

Akh: a brother by descent or a participant in a bond

In familial usage, akh denotes someone sharing a father or mother with another person.

Two people with the same father and mother are full brothers. Those sharing only a father or mother can likewise be called brothers in Arabic.

The word extends from this familial meaning to other relationships.

After describing brotherhood by descent and nursing, Al-Rāghib al-Iṣfahānī explains in Al-Mufradāt that akh also applies to people sharing a people, religion, occupation, transaction, friendship, or another connection.

This range shows that Arabic brotherhood is more than a biological relationship.

Participation in something alone does not, however, suffice to call all people brothers under every circumstance. The participation must constitute a recognized relationship between them in language and context.

Belonging to one people, sharing a religion, and belonging to one family, for example, are three distinct bonds, although the akh family can express all three.

Akh, akhū, akhā, and akhī

Akh belongs to Arabic nouns with special case forms.

In the familiar inflection of the “five nouns,” when akh is singular, not diminutive, and annexed to something other than the first-person possessive yāʾ, it takes wāw in the nominative, alif in the accusative, and yāʾ in the genitive: أَخُو (akhū), أَخَا (akhā), and أَخِي (akhī).

Thus أَخُوكَ (akhūka) is nominative, أَخَاكَ (akhāka) accusative, and أَخِيكَ (akhīka) genitive. In أَخِي (akhī) meaning “my brother,” however, the yāʾ is the first-person possessive pronoun, and case is analyzed through underlying, unexpressed vowel endings. This should not be conflated with the case-marking yāʾ in akhīka.

These differences create no independent familial or social meanings. The change in form concerns the word’s grammatical role in the sentence.

For example, أَخَاهُمْ (akhāhum) and أَخُوهُمْ (akhūhum) can both refer to their brother or fellow member of their people; the difference arises from their syntactic positions.

The dual is أَخَوَانِ (akhawāni), or in the accusative and genitive أَخَوَيْنِ (akhawayni).

In Al-Ḥujurāt 49:10, أَخَوَيْكُمْ (akhawaykum) refers to two brothers in the context of reconciliation between them.

Why is the root ʾ KH W?

Early morphological explanations trace the underlying form of akh to a form with final wāw.

The wāw in the dual akhawān and annexed forms such as akhūka is among the evidence offered for this analysis.

Arabic morphological classification must nevertheless be distinguished from historical etymology.

In Maqāyīs al-Lughah, Ibn Fāris proposes that the initial hamzah in akhw originally replaced wāw, relating the entry to a family concerning intention and turning toward something.

Many morphological explanations instead examine akhw through its recognized Arabic form.

The difference should not become a definitive claim that “brother” originally and necessarily meant “someone whose intention matches his brother’s intention.”

Such an explanation may propose a connection between meanings. The established, direct meaning of akh in Arabic is nevertheless brother or someone linked by brotherhood.

Ikhwah and ikhwān: does one mean kinship and the other religion?

Lexical explanations transmit a familiar distinction: ikhwah is used more often for brothers by descent, and ikhwān for friends and associates.

The tendency appears in many uses, but is not an exceptionless rule.

Abū Ḥātim al-Sijistānī explicitly rejects an absolute division between the plurals: both can apply to relatives and nonrelatives.

The Qur’an itself confirms this.

Al-Ḥujurāt 49:10 calls believers ikhwah, although biological brotherhood among all of them is not intended.

In Al-Nūr 24:61, ikhwānikum appears in a list of relatives whose houses are mentioned. There, ikhwān can therefore denote familial brothers.

Al-Nisāʾ 4:176 also contains إِخْوَةً رِجَالًا وَنِسَاءً (ikhwatan rijālan wa-nisāʾan), showing that ikhwah can occur in a construction concerning both brothers and sisters.

Forqan should therefore not always translate ikhwah as “blood brothers” and ikhwān as “religious friends.”

Both plurals belong to the family of brotherhood; context identifies the relationship.

Ukht: sister and a feminine counterpart

Ukht is the recognized feminine counterpart of akh.

Early morphological analysis connects its final tāʾ with the word’s historical structure and omitted wāw. Grammatical accounts differ over the details of this transformation.

Its plural is أَخَوَات (akhawāt), and its dual أُخْتَان (ukhtān) or أُخْتَيْن (ukhtayn).

Qur’anic ukht sometimes means a sister by descent, as with Mūsā’s sister following him.

Sometimes a milk-sister is mentioned in family rules.

In other uses, two groups or signs may be called one another’s sister because they are related or alike.

Just as akh is not confined to a blood brother, ukht does not express descent in every context.

An example from Arabic poetry

Poetry attributed to Miskīn al-Dārimī includes:

أَخَاكَ أَخَاكَ إِنَّ مَنْ لَا أَخَا لَهُ
كَسَاعٍ إِلَى الْهَيْجَا بِغَيْرِ سِلَاحِ

akhāka akhāka inna man lā akhā lahu / ka-sāʿin ilā al-hayjā bi-ghayri silāḥ

“Your brother, your brother—stand by him! For one who has no brother is like someone going to battle without a weapon.”

Here brotherhood is pictured as a bond of assistance and support.

Grammatical works also cite the verse for the repeated construction akhāka akhāka.

Its attribution is disputed, but sources including Khizānat al-Adab prefer the attribution to Miskīn al-Dārimī.

Miskīn al-Dārimī is an Islamic-period poet; this verse should therefore not be presented as securely identified pre-Islamic evidence.

Semantically, the verse alone does not establish whether the intended brother must be a relative or a close friend and ally. Literary explanations discuss both possibilities.

This accords with the breadth of brotherhood’s meaning in Arabic.

3. Brothers and sisters in the family: descent, nursing, and rights

Brotherhood in the account of Mūsā and Hārūn

Mūsā and Hārūn are a clear Qur’anic example of familial brotherhood.

Mūsā asks The God to appoint Hārūn alongside him, saying in Ṭā Hā 20:30:

هَارُونَ أَخِي

hārūna akhī

“Hārūn, my brother.”

Other verses refer to Hārūn as akhāhu or akhī.

This brotherhood accompanies cooperation in the message and assistance to Mūsā.

In Al-Qaṣaṣ 28:34, Mūsā says Hārūn is more eloquent than he and asks that he be sent alongside him.

Familial brotherhood in this account thus accompanies cooperation and shared responsibility.

This association does not mean that akh itself signifies minister, spokesman, or helper. Other clauses express these roles.

Nor does every brother by descent necessarily share his brother’s conduct and purpose.

Yūsuf and his brothers: kinship without moral agreement

Sūrat Yūsuf repeatedly uses akh, ikhwah, and their attached pronouns.

The account begins with Yūsuf’s relationship with his brothers and their jealousy, then describes separation, return, and renewed encounter.

In Yūsuf 12:5, Yaʿqūb warns Yūsuf not to tell his dream to his brothers, lest they plot against him.

This use matters because it shows that brotherhood by descent does not itself guarantee good or well-intentioned conduct.

Yūsuf 12:8 also names Yūsuf and his brother separately.

The distinction concerns their family relationship and the brothers’ perception of their father’s love.

Akh itself cannot supply every detail of their mothers’ relationships or the family’s structure; such matters require independent evidence.

At the account’s conclusion, Yūsuf mentions what Satan stirred up between him and his brothers.

A fraternal relationship may therefore suffer injustice and conflict, then find a way toward reconciliation.

Brotherhood here is actual kinship, but each person’s conduct is evaluated independently of it.

Mūsā’s sister

In Ṭā Hā 20:40 and Al-Qaṣaṣ 28:11, Mūsā’s sister has a role in his care and return to his family.

Ukht has its direct familial meaning in these verses.

Being his sister does not itself express all her roles, however. Her actions, following Mūsā, and speaking to others are stated in independent clauses.

Ukht should therefore not be defined lexically as caregiver or guardian, although Mūsā’s sister also performs such a role in the account.

A milk-sister

In Al-Nisāʾ 4:23, the Qur’an mentions أَخَوَاتُكُمْ مِنَ الرَّضَاعَةِ (akhawātukum mina al-raḍāʿah) among family bonds relevant to marriage rules.

The expression shows that Qur’anic “sister” can concern a relationship other than birth from shared parents.

Milk kinship is understood from the qualification mina al-raḍāʿah, however.

Ukht alone therefore does not determine whether someone is a sister by descent or nursing.

Nor should all legal conditions of nursing, such as its amount and other details, be extracted from the root أ خ و through that qualification.

Those questions require independent study of family rules.

Sisters and brothers in inheritance

Al-Nisāʾ 4:11, Al-Nisāʾ 4:12, and Al-Nisāʾ 4:176 use ikhwah, akh, and ukht in relation to inheritance.

Here family relationships matter for establishing financial rights.

In Al-Nisāʾ 4:176, ikhwatan rijālan wa-nisāʾan shows that both brothers and sisters are involved.

Al-Nisāʾ 4:12 also contains أَخٌ أَوْ أُخْتٌ (akhun aw ukht), a brother or sister.

The root أ خ و alone does not identify which kind of brother or sister is intended in each verse or how their shares are calculated.

The verses’ construction, stated conditions, and differences between the two rulings must be examined.

Al-Nisāʾ 4:11 also contains the plural ikhwah. The plural alone cannot resolve every question about the number of brothers and sisters required to affect the mother’s share; that needs separate grammatical and legal discussion.

4. Akhāhum: communal brotherhood and the Prophets’ bond with their audiences

One prominent Qur’anic use of the root introduces Prophets as their people’s brother.

Hūd, Ṣāliḥ, and Shuʿayb

Al-Aʿrāf, 7:65

وَإِلَىٰ عَادٍ أَخَاهُمْ هُودًا ۚ قَالَ يَا قَوْمِ اعْبُدُوا اللَّهَ مَا لَكُمْ مِنْ إِلَٰهٍ غَيْرُهُ ۚ أَفَلَا تَتَّقُونَ

wa-ilā ʿādin akhāhum hūdan; qāla yā qawmi uʿbudū allāha mā lakum min ilāhin ghayruhu; a-fa-lā tattaqūn

“To ʿĀd We sent their brother Hūd. He said: My people, serve The God; you have no god other than Him. Will you not be mindful?”

Hūd is introduced here as akhāhum, their brother.

Not everyone among ʿĀd follows Hūd’s invitation in the same account, however.

Brotherhood here therefore does not mean that every member of the people shares Hūd’s religion.

Communal affiliation and the Prophet’s belonging to his audience’s society offer a more suitable contextual reading.

A similar use occurs for Ṣāliḥ and Shuʿayb.

Al-Aʿrāf 7:73 calls Ṣāliḥ Thamūd’s brother.

Al-Aʿrāf 7:85 introduces Shuʿayb as Madyan’s brother.

These expressions show that brotherhood can arise from shared society and communal affiliation even where that society contains serious religious and moral disagreement.

Nūḥ and Lūṭ

Al-Shuʿarāʾ, 26:161

إِذْ قَالَ لَهُمْ أَخُوهُمْ لُوطٌ أَلَا تَتَّقُونَ

idh qāla lahum akhūhum lūṭun a-lā tattaqūn

“When their brother Lūṭ said to them: Will you not be mindful?”

In the same sūrah, Nūḥ in Al-Shuʿarāʾ 26:106, Hūd in Al-Shuʿarāʾ 26:124, and Ṣāliḥ in Al-Shuʿarāʾ 26:142 are introduced through akhūhum.

The construction places the Prophet in a close relationship with the people addressed.

But being a people’s brother must be distinguished from being each individual member’s biological brother.

The Qur’an does not say that every member of Lūṭ’s or Nūḥ’s people was born of the Prophet’s own parents.

Nor should calling the Prophet their brother imply that they all occupy the same position in faith.

Communal brotherhood and brotherhood in faith are distinct relationships.

The different addresses to Madyan and the People of Al-Aykah

Al-Shuʿarāʾ 26:177 names Shuʿayb in relation to the People of Al-Aykah without using akhūhum.

By contrast, the verses concerning Madyan introduce Shuʿayb as akhāhum.

The difference in expression is real and may matter in examining Shuʿayb’s relationship with Madyan and the People of Al-Aykah.

The absence of akhūhum from one verse alone does not, however, establish that the two communities must be entirely separate peoples or have no shared relationship.

The inclusion or omission of a description may have different contextual explanations.

A historical judgment about these communities requires independent examination of every relevant verse.

Ikhwānu Lūṭ

Qāf, 50:13

وَعَادٌ وَفِرْعَوْنُ وَإِخْوَانُ لُوطٍ

wa-ʿādun wa-firʿawnu wa-ikhwānu lūṭ

“And ʿĀd, Pharaoh, and the brothers of Lūṭ.”

Here ikhwānu Lūṭ appears in a list of earlier communities.

Within the network of verses about Lūṭ, the expression concerns a group with a social and historical relationship to him.

It should not be confined to Lūṭ’s brothers by descent.

Nor should ikhwān always be defined lexically as companions in faith, since this verse lists communities that denied the message.

This is another example of brotherhood being an actual social relationship without implying moral or religious agreement.

5. Brotherhood in faith and society, and moral relationships

Believers and brotherhood

Al-Ḥujurāt, 49:10

إِنَّمَا الْمُؤْمِنُونَ إِخْوَةٌ فَأَصْلِحُوا بَيْنَ أَخَوَيْكُمْ ۚ وَاتَّقُوا اللَّهَ لَعَلَّكُمْ تُرْحَمُونَ

innamā al-muʾminūna ikhwatun fa-aṣliḥū bayna akhawaykum; wa-ittaqū allāha laʿallakum turḥamūn

“The believers are brothers; so reconcile your two brothers, and be mindful of The God, that you may receive mercy.”

This is among the root’s most important uses beyond descent.

Brotherhood here is expressed on the basis of faith.

The Qur’an does more than employ an affectionate title: it immediately commands reconciliation between the two brothers.

This association shows that brotherhood in faith can form a basis for mutual responsibility.

Ikhwah itself nevertheless does not mean reconciliation or peace. The command comes from fa-aṣliḥū, “reconcile.”

The command also shows that disagreement can arise among believers. If brotherhood in faith meant the absence of every dispute, the command to reconcile them would have a different place.

Brotherhood here is therefore a relationship to be honored even during disagreement.

From enmity to brotherhood

Āl ʿImrān, 3:103

وَاعْتَصِمُوا بِحَبْلِ اللَّهِ جَمِيعًا وَلَا تَفَرَّقُوا ۚ وَاذْكُرُوا نِعْمَتَ اللَّهِ عَلَيْكُمْ إِذْ كُنْتُمْ أَعْدَاءً فَأَلَّفَ بَيْنَ قُلُوبِكُمْ فَأَصْبَحْتُمْ بِنِعْمَتِهِ إِخْوَانًا وَكُنْتُمْ عَلَىٰ شَفَا حُفْرَةٍ مِنَ النَّارِ فَأَنْقَذَكُمْ مِنْهَا ۗ كَذَٰلِكَ يُبَيِّنُ اللَّهُ لَكُمْ آيَاتِهِ لَعَلَّكُمْ تَهْتَدُونَ

wa-iʿtaṣimū bi-ḥabli allāhi jamīʿan wa-lā tafarraqū; wa-udhkurū niʿmata allāhi ʿalaykum idh kuntum aʿdāʾan fa-allafa bayna qulūbikum fa-aṣbaḥtum bi-niʿmatihi ikhwānan wa-kuntum ʿalā shafā ḥufratin mina al-nāri fa-anqadhakum minhā; ka-dhālika yubayyinu allāhu lakum āyātihi laʿallakum tahtadūn

“Hold fast together to the rope of The God, and do not become divided. Remember the blessing of The God upon you: when you were enemies, He joined your hearts, and through His blessing you became brothers. You were on the edge of a pit of fire, and He rescued you from it. Thus The God makes His signs clear to you, that you may be guided.”

Ikhwānan here results from a transformation of relationships among former enemies.

The important point is that the Qur’an does not confine this brotherhood to shared descent.

Former enemies became brothers through a new bond and the joining of hearts.

The verse does not establish that every social or intellectual disagreement disappears or that all believers acquire identical views on every subject.

Brotherhood in this context concerns the removal of enmity and the emergence of a new bond.

Allafa bayna qulūbikum, “He joined your hearts,” belongs to another root. Affectionate union and brotherhood are related here, but are not complete synonyms.

Brotherhood in religion and preserving descent

Al-Aḥzāb, 33:5

ادْعُوهُمْ لِآبَائِهِمْ هُوَ أَقْسَطُ عِنْدَ اللَّهِ ۚ فَإِنْ لَمْ تَعْلَمُوا آبَاءَهُمْ فَإِخْوَانُكُمْ فِي الدِّينِ وَمَوَالِيكُمْ ۚ وَلَيْسَ عَلَيْكُمْ جُنَاحٌ فِيمَا أَخْطَأْتُمْ بِهِ وَلَٰكِنْ مَا تَعَمَّدَتْ قُلُوبُكُمْ ۚ وَكَانَ اللَّهُ غَفُورًا رَحِيمًا

udʿūhum li-ābāʾihim huwa aqsaṭu ʿinda allāhi; fa-in lam taʿlamū ābāʾahum fa-ikhwānukum fī al-dīni wa-mawālīkum; wa-laysa ʿalaykum junāḥun fīmā akhṭaʾtum bihi wa-lākin mā taʿammadat qulūbukum; wa-kāna allāhu ghafūran raḥīmā

“Call them by their fathers’ names; that is more just with The God. If you do not know their fathers, they are your brothers in religion and your affiliates. There is no sin upon you for what you do mistakenly, but what your hearts deliberately intend is at issue. The God is forgiving and merciful.”

The verse distinguishes religious brotherhood from paternal descent.

The Qur’an emphasizes preserving family affiliation while also recognizing bonds of faith and society.

Brotherhood in faith should therefore not be treated as replacing actual descent.

Someone can be another’s brother in religion without being a child of the same father or mother.

Nor does the verse establish that not knowing one’s father deprives a person of every identity and social right. The verse itself also states a religious and social relationship.

Orphans: fa-ikhwānukum

Al-Baqarah 2:220 discusses orphans and uses fa-ikhwānukum in the context of improving their affairs and associating with them.

Brotherhood here is linked with social responsibility and proper association.

This does not mean that every orphan is biologically a brother to every guardian.

Nor does the title of brotherhood eliminate the orphan’s ownership of property.

The verse also concerns improvement and avoiding corruption. Brotherhood should therefore be understood within this framework of responsibility and respect for rights.

Brotherhood in religion after a change of position

Al-Tawbah 9:11 contains fa-ikhwānukum fī al-dīn, “then they are your brothers in religion.”

Here religious brotherhood accompanies conditions that the verse itself names.

Religious brotherhood is therefore more than descent or a tribal title.

This one expression should not, however, yield a general ruling about every person of another religion or every social relationship between them. The verse concerns a context of covenants, conflict, and changed conduct by the group addressed.

Brotherhood after death and in the Hereafter

Al-Ḥijr, 15:47

وَنَزَعْنَا مَا فِي صُدُورِهِمْ مِنْ غِلٍّ إِخْوَانًا عَلَىٰ سُرُرٍ مُتَقَابِلِينَ

wa-nazaʿnā mā fī ṣudūrihim min ghillin ikhwānan ʿalā sururin mutaqābilīn

“We removed all rancor from their breasts; as brothers, they are upon couches facing one another.”

Ikhwānan here accompanies the removal of rancor and facing one another.

The image places brotherhood within a relationship of peace and freedom from enmity.

Ikhwānan itself nevertheless does not mean couches or the absence of rancor. Independent words express those concepts in the verse.

Nor must everyone in this condition be a brother by descent.

Brotherhood in a wrongful path

Al-Isrāʾ, 17:27

إِنَّ الْمُبَذِّرِينَ كَانُوا إِخْوَانَ الشَّيَاطِينِ ۖ وَكَانَ الشَّيْطَانُ لِرَبِّهِ كَفُورًا

inna al-mubadhdhirīna kānū ikhwāna al-shayāṭīni; wa-kāna al-shayṭānu li-rabbihi kafūrā

“The squanderers are indeed brothers of the devils; and Satan is deeply ungrateful to his Lord.”

The verse shows that brotherhood does not always have positive value.

Here the fraternal bond is attributed to people who squander property and resources.

It should not be understood as biological descent shared by humans and Satan.

Brotherhood in this context concerns association or similarity in conduct and orientation.

Ikhwān itself does not mean squandering either: the word al-mubadhdhirīn identifies the squanderers’ conduct.

Al-Aʿrāf 7:202 also uses ikhwānuhum in a context of being drawn into error. Explanations differ over the pronouns’ precise referents, including a relationship between devils and their human associates.

Under any such reading, brotherhood is not necessarily biological or praiseworthy.

In Al-Ḥashr 59:11, the Qur’an likewise calls a group of disbelievers among the People of the Book the hypocrites’ “brothers,” and recounts the hypocrites’ promise to support them. This concerns cooperation and promised assistance, not a shared bond of faith among them all.

Thus brotherhood can exist in a path of truth or falsehood. The word itself expresses a relationship and association; its value is understood through the parties’ concerns and conduct.

6. Ukht beyond descent: the sister of groups and signs

Yā ukhta Hārūn

Maryam, 19:28

يَا أُخْتَ هَارُونَ مَا كَانَ أَبُوكِ امْرَأَ سَوْءٍ وَمَا كَانَتْ أُمُّكِ بَغِيًّا

yā ukhta hārūna mā kāna abūki imraʾa sawʾin wa-mā kānat ummuki baghiyyā

“O sister of Hārūn! Your father was not an evil man, nor was your mother an unchaste woman.”

The verse concerns Maryam, the mother of ʿĪsā.

Her audience addresses her as ukhta Hārūn, then mentions her father and mother.

Family affiliation and Maryam’s known background in the speakers’ eyes matter in this context.

There are several readings of precisely who Hārūn is, however.

Some relate the expression to Maryam’s family or ancestral connection with Hārūn, Mūsā’s brother.

Others understand Hārūn as another person in Maryam’s time, whether her actual brother or a man known for goodness and righteousness.

Some also interpret “sister of Hārūn” as affiliating Maryam with a righteous person’s path and qualities.

Linguistically, Arabic ukht can express relationships beyond a sister by descent.

This lexical possibility alone does not identify which Hārūn is intended in the verse.

Nor should the same name Hārūn in two periods lead, without examination, to the conclusion that the Qur’an identifies two historical figures as one person.

Conversely, one reading should not be declared certain solely on the basis of an external report.

What the verse itself makes clear is that the speakers use “sister of Hārūn” to affiliate Maryam with a known person or family, then compare her alleged conduct with her parents’ background.

The construction should be preserved in translation:

“O sister of Hārūn!”

Explaining Hārūn’s identity belongs to an independent reflection on Maryam 19:28.

Kullamā dakhalat ummatun laʿanat ukhtahā

In Al-Aʿrāf 7:38, the Qur’an describes groups entering the scene of punishment, each cursing a group affiliated with itself.

Ukhtahā here is attributed to a group or community.

Since ummah denotes a collective, ukhtahā cannot mean an individual’s biological sister.

This use indicates a comparable or associated group, connected with that community in conduct or fate.

Ukht itself does not determine the precise historical period or land in which the two groups lived.

Context and other evidence must establish those details.

Akbaru min ukhtihā: related signs

Al-Zukhruf, 43:48

وَمَا نُرِيهِمْ مِنْ آيَةٍ إِلَّا هِيَ أَكْبَرُ مِنْ أُخْتِهَا وَأَخَذْنَاهُمْ بِالْعَذَابِ لَعَلَّهُمْ يَرْجِعُونَ

wa-mā nurīhim min āyatin illā hiya akbaru min ukhtihā wa-akhadhnāhum bi-al-ʿadhābi laʿallahum yarjiʿūn

“We showed them no sign except that it was greater than its counterpart; and We seized them with punishment, that they might return.”

Ukhtihā here refers to another sign in the same set.

Ukht therefore means neither a biological sister nor a woman here.

The signs may be described as one another’s “sister” because they belong to one set or share a relationship in kind and function.

This expression does not establish that all the signs are identical in intensity and magnitude.

The verse itself says that each sign was greater than its sister.

The use shows that similarity and relationship are compatible with differences in magnitude or rank.

Ukht here is also better explained as “a related sign” or “a comparable sign,” rather than merely “the previous sign,” since temporal precedence does not necessarily follow from ukht’s own meaning.

7. Related roots and translation proposals

Akh and ṣāḥib

Study of Ṣ Ḥ B

Ṣāḥib belongs to ص ح ب (Ṣ Ḥ B), concerning companionship and association.

Akh can also describe a friend or companion, but its basic meaning expresses kinship or a relationship resembling brotherhood.

Not every ṣāḥib or companion is therefore necessarily a brother.

Someone may travel or sit with another for a time without a close familial or social relationship between them.

Conversely, a biological brother may be separated from his brother for years without losing the family relationship.

Akh and walī

Study of W L Y

Walī in Arabic concerns nearness, guardianship, assistance, and other relationships.

Akh can likewise accompany assistance and support in some contexts.

Not every brother is a walī, however, nor is every walī a biological or religious brother.

Al-Tawbah 9:23 mentions brothers and fathers in a discussion of walāyah, affiliation or protective allegiance. This association shows that family relationship and walāyah are related but distinct matters.

Akh itself should therefore not be defined lexically as guardian or holder of authority.

Akh and qarīb

Study of Q R B

Qarīb concerns nearness and can denote a relative or spatial and figurative closeness.

Akh expresses a particular kind of kinship or fraternal relationship.

A brother by descent is a relative, but not every relative is a brother.

Religious brotherhood can also exist between people without shared descent.

Akh and ṣadīq

Study of Ṣ D Q

Ṣadīq concerns friendship and a relationship of sincerity and closeness.

Akh can likewise be used of a close friend.

The words overlap in this use.

A brother by descent may nevertheless disagree with or be hostile to his brother while the biological relationship persists.

Familial brotherhood therefore does not depend on actual friendship being present.

Akh and ukht

Both belong to one root family.

Akh is the masculine and ukht the feminine form of the brother-sister relationship.

In the Qur’an, both can extend beyond descent.

Al-Zukhruf 43:48 calls one sign another’s sister.

Al-Aʿrāf 7:38 calls one community another’s sister.

In verses concerning the Prophets, a person can likewise be his people’s brother.

These uses show Arabic drawing upon family relationships to express connection and similarity.

They should not imply actual biological descent shared by phenomena or groups.

Translation proposals for Forqan

In uses concerning descent, “brother” and “sister” are suitable direct equivalents.

Depending on context, ikhwah and ikhwān can be translated as “brothers,” “sisters and brothers,” “fellow believers,” or “close associates.”

“Brothers” should nevertheless not be removed without reason where the image of brotherhood matters to the verse’s argument.

In Al-Ḥujurāt 49:10:

“The believers are brothers; so reconcile your two brothers.”

In Āl ʿImrān 3:103:

“Through the blessing of The God, you became brothers.”

In the verses about Hūd, Ṣāliḥ, and Shuʿayb:

“Their brother Hūd,” “their brother Ṣāliḥ,” and “their brother Shuʿayb.”

An explanation should clarify that this relationship is communal in context, not necessarily brotherhood in faith.

In Al-Isrāʾ 17:27:

“The squanderers are brothers of the devils.”

This should be explained through association and similarity of conduct, rather than actual descent.

In Maryam 19:28:

“O sister of Hārūn!”

Hārūn’s identity and the nature of Maryam’s connection to him should be examined in the reflection on that verse.

In Al-Zukhruf 43:48:

“Each sign was greater than its comparable sign.”

In Al-Aʿrāf 7:38:

“Every community curses the community affiliated with it.”

Conclusion

The Arabic root أ خ و is recognized through the relationship of brother and sister.

The relationship is initially familial, but recognized Arabic and Qur’anic uses can also express milk kinship, communal, religious, and social bonds, and association in a shared path or characteristic.

The family occurs 96 times in the Qur’an.

Mūsā and Hārūn exemplify familial brotherhood. Yūsuf and his brothers show that shared descent does not itself guarantee good conduct.

Prophets including Hūd, Ṣāliḥ, Shuʿayb, Nūḥ, and Lūṭ are called their people’s “brother” in particular contexts, even where religious disagreement exists between them and their people.

Believers are also described as ikhwah and commanded to reconcile one another when disagreement arises.

Conversely, the Qur’an calls people who squander resources ikhwāna al-shayāṭīn. Brotherhood in its own lexical meaning is therefore neither invariably a mark of faith nor invariably a moral virtue.

Ukht exhibits a similar range. A sister can be related through family or nursing, but a community can also be another community’s sister and a sign another sign’s sister.

The distinction between ikhwah and ikhwān should likewise not become an absolute division between descent and friendship. The Qur’an uses both forms within and beyond kinship.

For Forqan, the basic definition of this family is as follows: akh and ukht denote brother and sister, initially in a familial bond and, more broadly, people or things connected through descent, peoplehood, religion, a path, cooperation, or a shared characteristic. Ikhwah and ikhwān are two plural forms in this family whose ranges of use overlap.

Context must identify the kind of brotherhood and its value; the word alone does not.

Accordingly, the principal question in each verse is: what bond underlies this brotherhood or sisterhood—descent, nursing, peoplehood, faith, friendship, cooperation, or similarity of conduct?

Recognizing that bond clarifies the precise meaning of each Qur’anic use.
