Quraanic Verses on Hijab

O ye children of Adam! We have bestowed raiment upon you to cover your shame, as well as to be an adornment to you, But the raiment of righteousness,― that is the best. Such are among the signs of Allah, that they may receive admonition! (7:26)

And say to the believing women that they should lower their gaze and guard their modesty; that they should not display their beauty and ornaments except what (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. And O ye Believers! Turn ye all together towards Allah that ye may attain Bliss. (24:31)

O prophet! tell thy wives and daughters, and the believing women, that they should cast their outer garments over their persons (when abroad): that is most convenient, that they should be known (as such) and not molested: and Allah is Oft-Forgiving, Most Merciful. (33:59)
