Purdah (Veil)

O ye who believe! enter not houses other than your own, until ye have asked permission and saluted those in them: that is best for you, in order that ye may heed (what is seemly).24.27

If ye find no one in the house, enter not until permission is given to you: if ye are asked to go back, go back: that makes for greater purity for yourselves: and Allah knows well all that ye do.24.28

It is no fault on your part to enter houses not used for living in, which serve some (other) use for you: And Allah has knowledge of what ye reveal and what ye conceal.24.29

Say to the believing men 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.24.30

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 (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 husband's 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

But when the children among you come of age, let them (also) ask for permission, as do those senior to them (in age): Thus does Allah make clear His Signs to you: for Allah is full of knowledge and wisdom.24.59

O Consorts of the Prophet! Ye are not like any of the (other) women: if ye do fear (Allah), be not too complacent of speech, lest one in whose heart is a disease should be moved with desire: but speak ye a speech (that is) just. 33.32
And stay quietly in your houses, and make not a dazzling display, like that of the former Times of Ignorance; and establish regular Prayer, and give regular Charity; and obey Allah and His Messenger. And Allah only wishes to remove all abomination from you, ye members of the Family, and to make you pure and spotless. 33.33

O ye who believe! Enter not the Prophet's houses,- until leave is given you,- for a meal, (and then) not (so early as) to wait for its preparation: but when ye are invited, enter; and when ye have taken your meal, disperse, without seeking familiar talk. Such (behaviour) annoys the Prophet: he is ashamed to dismiss you, but Allah is not ashamed (to tell you) the truth. And when ye ask (his ladies) for anything ye want, ask them from before a screen: that makes for greater purity for your hearts and for theirs. Nor is it right for you that ye should annoy Allah's Messenger, or that ye should marry his widows after him at any time. Truly such a thing is in Allah's sight an enormity. 33.53

There is no blame (on these ladies if they appear) before their fathers or their sons, their brothers, or their brother's sons, or their sisters' sons, or their women, or the (slaves) whom their right hands possess. And, (ladies), fear Allah; for Allah is Witness to all things.33.55

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
