O you who believe, do not enter other houses except yours without first asking permission and saluting the inmates. This is better for you: You may haply take heed. 27 And if you find not anyone therein, enter it not until leave is given to you. And if you are told, 'Return,' return; that is purer for you; and God knows the things you do. 28 [On the other hand,] you will incur no sin if you [freely] enter houses not intended for living in but serving a purpose useful to you: but [always remember that] God knows all that you do openly, and all that you would conceal. 29 Say to the believing men that they cast down their looks and guard their private parts; that is purer for them; surely Allah is Aware of what they do. 30 And say to the believing women, that they lower their gaze cast down their eyes and guard their chastity, and do not reveal their adornment except that which is outward (face and hands); and let them draw their veils over their neck, and not reveal their adornment except to their husbands, or their fathers, or their husbands' fathers, or their sons, or their husbands' sons, or their brothers, or their brothers' sons, or their sisters' sons, or their women, or what their right hands own, or such male attendants having no sexual desire, or children who have not yet attained knowledge of women's private parts; nor let them stamp their feet, so that their hidden ornament is known. And, O believers turn to Allah all together, in order that you prosper. 31 And wed the single among you and the fit ones among your male and female slaves; if they are poor, Allah will enrich them of His grace; Allah is Ample, Knowing. 32 But let them who find not [the means for] marriage abstain [from sexual relations] until Allah enriches them from His bounty. And those who seek a contract [for eventual emancipation] from among whom your right hands possess - then make a contract with them if you know there is within them goodness and give them from the wealth of Allah which He has given you. And do not compel your slave girls to prostitution, if they desire chastity, to seek [thereby] the temporary interests of worldly life. And if someone should compel them, then indeed, Allah is [to them], after their compulsion, Forgiving and Merciful. 33 And assuredly We have sent down unto you revelations illuminating and a similitude for those who passed away before you and an exhortation unto the God-fearing. 34
