A common claim today is that hijab is only a cultural custom, not an Islamic requirement, because the Quran uses the word hijab for a screen or barrier rather than for a headscarf. The vocabulary point is partly true, but the conclusion is false. The ruling does not depend on the modern label "hijab"; it rests on the Quranic commands concerning khimar and jilbab, the Sunnah, and the settled understanding of the jurists.
The claim
The argument usually says: the Quran does not command women to "wear hijab" as that phrase is used today; therefore covering the hair is a later cultural import. In its more accurate form, the objection notes that the word hijab occurs in the Quran with meanings such as barrier, screen, or separation, not as the technical name for a headscarf.
But Islamic rulings are derived from the meanings of the revealed texts, not from whether a modern English or Arabic label appears. The Quran legislates this matter using more direct clothing terms: khimar and jilbab.
The Quran commands the covering
The obligation does not rest on the word hijab. It rests on explicit Quranic commands.
1. The verse of the khimar (24:31)
And tell the believing women to lower their gaze and guard their chastity, and not to display their adornment except what appears of it, and to draw their khumur over their juyub...
Quran 24:31
Khumur is the plural of khimar. In Arabic, a khimar is a covering, and when used for a woman it refers to the covering worn over the head. Juyub is the plural of jayb, meaning the opening of the garment at the neck and chest. The verse therefore commands believing women to draw their head-coverings down over the neck opening and chest, instead of leaving the neck and bosom exposed.
This is how the classical commentators explained the verse. Al-Tabari, al-Qurtubi, Ibn Kathir, and others mention that women had head-coverings but would leave the neck and upper chest exposed, so they were commanded to draw the khimar over the jayb. The early discussion over the phrase "except what appears of it" concerned matters such as outer clothing, or according to many scholars the face and hands; it was not understood as permission to expose the hair, neck, or bosom.
The first Muslim women, who understood the Arabic of revelation directly, acted on the verse immediately. Aisha (may Allah be pleased with her) said:
May Allah have mercy on the first emigrant women. When Allah revealed, "and to draw their khumur over their juyub," they tore their garments and covered themselves with them.
Sahih al-Bukhari 4758
The generation that received Quran 24:31 did not take it as a vague call to inner modesty only. They took it as a practical command to cover.
2. The verse of the jilbab (33:59)
O Prophet, tell your wives and your daughters and the women of the believers to draw their jalabib over themselves. That is more suitable, so that they may be recognized and not harmed...
Quran 33:59
Jalabib is the plural of jilbab, an outer garment or wrap worn over ordinary clothing. This verse is addressed not only to the wives of the Prophet (PBUH), but also to his daughters and the women of the believers. It commands believing women to draw the outer garment over themselves in public. It also mentions a wisdom: that they be recognized and not harmed. A wisdom stated in the verse does not cancel the command.
Umm Salamah (may Allah be pleased with her) reported the immediate practice of the women of the Ansar when this verse was revealed:
When the verse, "They should draw their outer garments over themselves," was revealed, the women of the Ansar came out as if crows were over their heads because of the outer garments they wore.
Sunan Abi Dawud 4101 (graded sahih by al-Albani)
The report shows that they understood the verse as a command of visible covering from above the head and over the body. It is evidence for covering; it does not mean that black is the only permissible color.
The Sunnah confirms the public outer covering
The Prophet (PBUH) treated the outer covering as an expected requirement for women going out, not as a decorative custom. When he commanded the women to attend the Eid gathering, Umm Atiyyah (may Allah be pleased with her) mentioned a practical problem:
She said, "O Messenger of Allah, one of us may not have a jilbab." He said, "Let her sister dress her in one of her jilbabs."
Sahih Muslim 890
He did not tell her to attend without an outer garment; he instructed that one be provided for her. This supports what the Quranic verses indicate: the jilbab was not a mere fashion item, but part of the expected public covering.
A further narration, often cited by jurists as corroborating evidence though disputed in its chain, reports that Asma bint Abi Bakr entered upon the Prophet (PBUH) wearing thin clothing, and he said:
O Asma, when a woman reaches the age of menstruation, it is not proper that anything be seen of her except this and this - and he pointed to his face and hands.
Sunan Abi Dawud 4104 (Abu Dawud noted that it is mursal because Khalid ibn Durayk did not meet Aisha)
This report should not be made the main proof on its own. Some scholars considered it strengthened by supporting routes, while others did not. Either way, the obligation to cover the hair does not depend on this narration. It is already established by Quran 24:31, Quran 33:59, the authentic practice reported from the first Muslim women, and the authentic hadith concerning the jilbab.
The consensus of the scholars
The legal conclusion is not a modern inference. The four Sunni schools hold that an adult Muslim woman must cover her hair, neck, and body before non-mahram men, except for what the Law permits to remain apparent. The well-known juristic disagreements concern details such as the face, hands, feet, and circumstances of fitnah; they do not concern whether the hair may be uncovered before non-mahrams as a normal practice.
In other words, there is consensus on the core ruling: covering the hair is obligatory. Different cultures may use different styles, garments, and names, but the obligation itself is not cultural.
Why the "word hijab" objection fails
The word hijab does occur in the Quran, but it is used for meanings such as a barrier or screen. In Quran 33:53, for example, it refers to a screen in relation to the Mothers of the Believers. It is true that Quran 24:31 does not use the word hijab for the head-covering; it uses khimar. Quran 33:59 uses jilbab. That does not weaken the ruling - it strengthens it, because the Quran uses the actual clothing terms relevant to the command.
Arguing that the obligation is absent because one preferred label is absent is like denying a law about "protective headgear" because it does not use the word "helmet." The command is present; only the modern shorthand is different.
Conclusion
Hijab, in the sense of the prescribed covering of a Muslim woman before non-mahram men, is mandatory. It is grounded in Quran 24:31 and Quran 33:59, confirmed by authentic hadith and the practice of the first generation, and affirmed by the Sunni schools. The exact style of covering may vary by culture, but the obligation to cover the hair, neck, and body is not a cultural invention.
