Qur’anic Root J B N

1. Forms and three branches of meaning

The root J B N occurs only once in the Qur’an, as الْجَبِينِ with the preposition li-, in Al-Ṣāffāt 37:103. No verb, verbal noun, or other form of this family occurs in the Qur’an.

Quranic Arabic Corpus: sole occurrence in Al-Ṣāffāt 37:103

In early Arabic, this family has three principal branches.

جَبِين (jabīn): the side of the forehead, on its right or left. Its dual is جَبِينان (jabīnān). Lexical sources also record plurals such as أَجْبُن (ajbun) and أَجْبِنَة (ajbinah).

جُبْن (jubn) and جَبَان (jabān): cowardice and a person who hangs back from advancing or confronting danger. جَبُنَ (jabuna) means to be cowardly or fainthearted; جَبَّنَهُ (jabbanahu) is recorded for judging someone cowardly or attributing cowardice to them.

جُبْن (jubn): the familiar food made from milk: cheese. Vocalizations such as جُبُن (jubun) and جُبُنّ (jubunn) are also recorded. تَجَبَّنَ اللَّبَنُ (tajabbana al-labanu) means that milk became like cheese.

These three branches are established in Arabic, but their shared letters J B N do not prove that all arose from a single material image or original meaning.

Ibn Fāris writes explicitly in Maqāyīs al-Lughah:

«الْجِيمُ وَالْبَاءُ وَالنُّونُ ثَلَاثُ كَلِمَاتٍ لَا يُقَاسُ بَعْضُهَا بِبَعْضٍ.»

al-jīmu wa-al-bāʾu wa-al-nūnu thalāthu kalimātin lā yuqāsu baʿḍuhā bi-baʿḍin

That is: “Jīm, bāʾ, and nūn comprise three words, none of which is explained by analogy with another.”

He then names cheese, cowardice, and the two sides of the forehead.

Ibn Fāris, Maqāyīs: three independent branches

This judgment prevents us from manufacturing an apparently unified definition by deriving cowardice from a physical feature of the forehead or connecting cheese to weakness of heart through an invented explanation.

Preserving three independent branches is more accurate than constructing an unsupported common semantic core. Brief root meaning: three distinct branches: the side of the forehead, cowardice, and cheese; in the Qur’an: the side of the forehead.

2. Jabīn in Arabic: its location on the face

In Arabic, jabīn is closely related to jabhah, but the two are not completely identical.

جَبْهَة (jabhah) denotes the front, central upper part of the face: the forehead. In more precise lexical usage, جَبِين (jabīn) denotes one of its two sides.

In the usual lexical explanation, a person has two jabīns: one on the right and one on the left of the forehead.

Lisān al-ʿArab quotes Al-Layth:

«الْجَبِينُ فَوْقَ الصُّدْغِ، وَهُمَا جَبِينَانِ عَنْ يَمِينِ الْجَبْهَةِ وَشِمَالِهَا.»

al-jabīnu fawqa al-ṣudghi wa-humā jabīnāni ʿan yamīni al-jabhati wa-shimālihā

That is: “The jabīn is above the temple; there are two jabīns, to the right and left of the forehead.”

صُدْغ (ṣudgh) denotes the side of the head near the outer corner of the eye and the temple. The jabīn is therefore the region above this area, beside the central forehead.

Some lexical descriptions extend the jabīn from the eyebrow region to the hairline. Sources nevertheless differ over its precise boundaries and whether it is treated as a continuous region or as two separate sides.

Lisān al-ʿArab: boundaries and the two sides of the forehead

These differences should not lead us to restrict the word to an extremely small, precisely fixed point on the face.

Its defensible meaning is the lateral part of the forehead: a region that can ordinarily be called “the side of the forehead.”

Is jabīn simply the forehead?

In modern Persian, jabīn commonly means the forehead. Expressions referring to a high brow, the sweat of one’s brow, or a furrowed brow illustrate this usage.

Some literary evidence also presents a broader Arabic use of jabīn for the forehead.

Early lexical sources nevertheless clearly record the distinction between the two sides of the forehead and its central part.

Translating jabīn simply as “forehead” in Persian is therefore neither unintelligible nor unrelated. To preserve the Arabic word’s more precise spatial meaning, however, “the side of the forehead” is preferable.

This distinction matters especially in the verse in Al-Ṣāffāt, because the sentence concerns the position in which Abraham’s son’s head was placed.

3. Other uses in early Arabic

Cowardice and faintheartedness

In the branch concerning human behavior, جُبْن (jubn) stands in opposition to courage.

Al-Rāghib al-Iṣfahānī explains it as follows:

«ضَعْفُ الْقَلْبِ عَمَّا يَحِقُّ أَنْ يَقْوَى عَلَيْهِ.»

ḍaʿfu al-qalbi ʿammā yaḥiqqu an yaqwā ʿalayhi

That is: “Weakness of heart in the face of something against which it ought to be strong.”

Al-Rāghib, Al-Mufradāt: faintheartedness and forms of J B N

This explanation shows an important distinction between natural fear and cowardice.

Fear is a reaction experienced when danger is perceived; it is not always blameworthy in itself. In ethical usage, cowardice denotes a condition in which fear keeps someone from doing something they have the ability or responsibility to confront.

The word jubn does not, however, specify every detail concerning duty, responsibility, or the rightness of an action. Judging whether someone’s withdrawal was cowardice or prudent caution depends on the situation and other evidence.

جَبَان (jabān) describes someone known for cowardice. Its plural is جُبَنَاء (jubanāʾ). Early sources also record jabān for a woman, alongside the form جَبَانَة (jabānah).

In one of its uses, أَجْبَنْتُهُ (ajbantuhu) means finding or considering someone cowardly, whereas جَبَّنْتُهُ (jabbantuhu) can mean attributing cowardice to them. The form جَبِين (jabīn) is also recorded in the cowardice branch for a cowardly person. Its identical form to the body-part noun does not remove the need to examine context.

Lisān al-ʿArab: jabīn also recorded in the cowardice branch

These two uses should be distinguished. Thinking someone cowardly does not necessarily establish their actual cowardice. Attributing a characteristic to someone is also distinct from their having that characteristic.

A statement attributed to ʿAmr ibn Maʿdīkarib about a group he had fought reads:

«قَاتَلْتُهَا فَمَا أَجْبَنْتُهَا.»

qātaltuhā fa-mā ajbantuhā

That is: “I fought them and did not find them cowardly.”

This witness shows that أَجْبَنَ (ajbana) can concern an assessment of another’s courage or cowardice.

ʿAmr ibn Maʿdīkarib lived across the pre-Islamic and Islamic periods, and this statement is transmitted in an account of his life. Without dating the event and its transmission, it should not be treated as definite pre-Islamic evidence. The same expression occurs in the account of his visit to Mujāshiʿ ibn Masʿūd in Basra; this setting provides a report from the Islamic period, rather than establishing a pre-Qur’anic date for the statement.

Al-Zamakhsharī, Rabīʿ al-Abrār, chapter 86: ʿAmr’s visit in Basra

Cheese and the transformation of milk

In the food branch, جُبْن (jubn) denotes cheese.

Lexical sources record several vocalizations, including forms with ḍammah on both jīm and bāʾ and forms with a doubled nūn.

تَجَبَّنَ اللَّبَنُ (tajabbana al-labanu) means that milk became like cheese. اجْتَبَنَ اللَّبَنَ (ijtabana al-labana) is also recorded for making cheese from milk.

Lisān al-ʿArab: forms for cheese and its preparation

This usage concerns a food and its transformation, rather than human fear or a part of the face.

One might imagine similarities between milk becoming firm and certain bodily states. Such resemblance alone, however, is insufficient to establish a common etymological origin.

There is no need to connect cheese, cowardice, and the side of the forehead through an invented theory of “gathering,” “hardening,” or “hanging back.”

Jabbānah: open land and a cemetery

Arabic also uses جَبَّان (jabbān) and جَبَّانَة (jabbānah), with a doubled bāʾ, for open, level land, desert terrain, and ground outside a settlement.

In some regions, cemeteries were also called jabbānah because they occupied open ground outside inhabited areas.

Lexical descriptions sometimes apply this word to level land with few trees and sometimes to relatively elevated ground suitable for vegetation.

This branch should not be confused with جَبَان (jabān), a cowardly person, despite the similar written forms.

Calling a cemetery jabbānah does not establish that its name arose from fear of the dead or human cowardice. Lexical sources explain this usage through the cemetery’s location on open ground.

Lisān al-ʿArab: jabbānah and open ground

This example again shows that shared letters and even similar sound do not establish a single meaning.

4. Qur’anic use: the side of Abraham’s son’s forehead

Al-Ṣāffāt 37:103

فَلَمَّا أَسْلَمَا وَتَلَّهُ لِلْجَبِينِ

fa-lammā aslamā wa-tallahu li-al-jabīni

“When they both surrendered, and he laid him down upon the side of his forehead,”

This verse continues the account of Abraham and his son.

In Al-Ṣāffāt 37:102, Abraham describes a dream in which he sees himself slaughtering his son and asks his opinion. His son expresses readiness for what his father is commanded to do.

Al-Ṣāffāt 37:103 then describes their surrender and the son being laid upon the side of his forehead.

Understanding this sentence requires distinguishing three elements: أَسْلَمَا (aslamā), وَتَلَّهُ (wa-tallahu), and لِلْجَبِينِ (li-al-jabīni).

أَسْلَمَا (aslamā) belongs to S L M and concerns both of them surrendering in this context.

Study of S L M

تَلَّهُ (tallahu) belongs to T L L and concerns casting down, laying someone on the ground, or placing them in a fallen position.

Study of T L L

الْجَبِين (al-jabīn), however, names a particular part of the head. By itself it conveys neither surrendering nor casting down.

The action and position are therefore understood from the whole sentence, rather than from the lexical meaning of jabīn alone.

Why li-al-jabīni rather than li-al-jabhati?

This difference in the verse’s choice of word deserves attention.

If jabīn is understood in its more precise lexical sense as one of the two sides of the forehead, the sentence describes the son’s head positioned on its side or upon the side of his forehead.

Jabhah, by contrast, refers to the central part of the forehead.

This distinction can help us envisage the head’s position. It does not mean that the verse describes the body’s entire posture or the exact manner in which the son was placed.

The word jabīn alone cannot, for example, establish whether the son lay on his right or left side, whether his hands were bound, or the angle of his head.

The text indicates the region of the head in contact with the ground and the general act of laying him down. Other details cannot be recovered from this word itself.

The role of li- in li-al-jabīni

The preposition li- here should not be translated with its common sense “for.”

In context, تَلَّهُ لِلْجَبِينِ (tallahu li-al-jabīni) conveys the direction or position in which someone is laid upon the side of the forehead. In constructions of this kind, Arabic lām can have a sense close to عَلَى (ʿalā), “upon.”

The rendering “he laid him down upon the side of his forehead” is therefore defensible in the sentence’s structure and meaning.

This meaning arises from the combination of the verb talla, the preposition lām, and the noun jabīn. Jabīn itself does not mean “placing on the ground” or “laying on one’s side.”

Does the verse concern fear or cowardice?

Because the letters are shared, one might try to establish a semantic connection between jabīn and jubn, “cowardice.”

Such a reading has no lexical support in this verse.

Al-jabīn is a body-part noun here, occurring with a verb that describes the son’s physical position.

There is no contextual indication that this word means fear, weakness of heart, or retreat from danger in this sentence.

In the preceding verse, Abraham’s son speaks of patience and perseverance. This contextual connection does not mean that jabīn itself has become a symbol of courage or cowardice.

The son’s perseverance is understood from his speech and conduct, rather than by turning the side of the forehead into an ethical characteristic.

The Qur’anic text and narrative details

Some exegetical reports explain that the son asked his father to place him on the ground in a way that would keep him from looking at his face while carrying out the act.

Such reports seek to explain the reason for the head’s position. The verse itself does not state this conversation or motive.

From وَتَلَّهُ لِلْجَبِينِ (wa-tallahu li-al-jabīni), one can only understand that Abraham laid his son in a position upon the side of his forehead. The reason for choosing this position, the body’s precise contact with the ground, and any accompanying conversation are not established by this expression itself.

Al-Ṭabarī: jabīn and the distinction between transmitted reports and the text

Al-Ṣāffāt 37:103 also does not state that the slaughter was carried out. Al-Ṣāffāt 37:104, Al-Ṣāffāt 37:105, Al-Ṣāffāt 37:106, and Al-Ṣāffāt 37:107 describe the call to Abraham, fulfillment of the vision, the manifest trial, and the son’s ransom with a great sacrifice.

The description of the son being laid upon the side of his forehead is therefore part of this narrative sequence, rather than a report that he was actually slaughtered.

5. Distinctions from related roots

J B N (jabīn) and J B H (jabhah)

These roots differ in structure but are close within the semantic field of parts of the face.

In more precise usage, jabīn is the side of the forehead, whereas jabhah denotes its front, central part.

In Al-Tawbah 9:35, جِبَاهُهُمْ (jibāhuhum) belongs to J B H.

This word is the plural of jabhah, rather than of jabīn.

Study of J B H

The fact that both words concern the forehead does not justify merging the two roots or automatically substituting one for the other in Qur’anic translation.

J B N (jabīn) and J N B (janb)

جَنْب (janb), from J N B, concerns the side or flank of something.

This concept can help explain the bodily position in Al-Ṣāffāt 37:103, since resting upon the side of the forehead may accompany lying on one’s side.

Janb and jabīn nevertheless denote neither the same body part nor the same root.

Jabīn refers to a particular region of the head, whereas janb has the broader range of side or flank.

Study of J N B (Not yet published)

If an explanation says that the son was placed on his side, this is an interpretation of the body’s position, rather than a direct translation of jabīn itself.

J B N (jubn) and KH W F (khawf)

خَوْف (khawf) concerns fear and apprehension in the Qur’an. It can arise in different situations, from actual danger to concern about the future.

In Arabic ethical usage, jubn concerns faintheartedness and failure to confront something.

Khawf and jubn can therefore be related, but they are not identical.

Study of KH W F

Someone who fears danger is not necessarily cowardly. Even a courageous person may recognize and fear danger but confront it when necessary.

Conversely, fear may cause someone to avoid a responsibility they bear.

This distinction helps in studying Arabic cowardice terminology, but it should not be imported into the translation of al-jabīn in Al-Ṣāffāt: the Qur’an does not use this root in the cowardice sense.

6. Translation proposals for Forqan

In this root’s Qur’anic use, jabīn means the side of the forehead.

Jabīn is a familiar Persian word. Because ordinary Persian usage also applies it to the whole forehead, using it without explanation may conceal the Arabic distinction between jabīn and jabhah.

“The side of the forehead” is a clearer, more precise equivalent.

The existing Persian Forqan translation of Al-Ṣāffāt 37:103, rendered here in English, reads:

“When they both surrendered, and he laid him down upon the side of his forehead,”

This translation preserves the verse’s main structure and conveys the indicated position without adding historical or exegetical details.

A brief word explanation may read:

“Jabīn: one of the two sides of the forehead, on its right or left.”

For this particular verse:

“Li-al-jabīni: upon the side of his forehead; referring to the position of Abraham’s son when he was laid on the ground.”

“Cowardice,” “inward surrender,” and “patience” should not be added to the meaning of jabīn itself.

Conclusion

The Arabic root J B N has several branches of meaning, chiefly the side of the forehead, cowardice, and cheese.

Ibn Fāris explains these three branches independently and rejects explaining one by analogy with another. Other lexical sources likewise show that they cannot all be derived from a single original meaning without reliable evidence.

Only al-jabīn from this family occurs in the Qur’an, in Al-Ṣāffāt 37:103. It denotes the side of the forehead, rather than cowardice or a food.

In Abraham’s account, jabīn helps identify his son’s physical position. The Qur’an says that he was laid upon the side of his forehead, but this expression does not establish the body’s precise angle, the position of his hands, or the motive for choosing that posture.

The direct, defensible meaning of Qur’anic jabīn is the side of the forehead. The root’s other branches matter for understanding the Arabic lexical field, but should not be imposed on its sole Qur’anic occurrence.
