Is It Mandated by the Qu'ran?
Hijab and modest dressing is mandated in the Qur’an, though some Muslims argue that it is not a strict requirement but merely a strong suggestion (that is open to individual interpretation. A few passages in the Qur’an refer to an Islamic dress code:
"Say to the believing man that they should lower their gaze and guard their modesty; that will make for greater purity for them; and Allah is well acquainted with all that they do. And say to the believing women that they should lower their gaze and guard their modesty; and that they should not display their beauty and ornaments except what must ordinarily appear thereof; that they should draw their veils over their bosoms and not display their beauty except to their husbands, their fathers, their husbands' fathers, their sons, their husbands' sons, their brothers or their brothers' sons, or their sisters' sons, or their women, or the slaves whom their right hands possess, or male servants free of physical needs, or small children who have no sense of the shame of sex; and that they should not strike their feet in order to draw attention to their hidden ornaments ..." (Qur'an 24:30-31)
This verse highlights three points: That a woman shouldn’t show her beauty except when faced with uncontrolled factors, like the wind blowing her clothes; that the headscarf should cover the hair, neck, and the bosom; and that women need not cover up in front of certain men (husbands, fathers, sons, etc.).
