O you who believe! Do not enter houses other than your own houses until you have asked permission and saluted their inmates; this is better for you, that you may be mindful. 27 And if you do not find anyone there, do not enter it until permission is given to you. And if you are told 'Return', so return, that is purer for you; and Allah 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 believers, that they cast down their eyes and guard their private parts; that is purer for them. God is aware of the things they work. 30 And tell the believing women to lower their gaze and to be mindful of their chastity, and not to display their charms [in public] beyond what may [decently] be apparent thereof; hence, let them draw their head-coverings over their bosoms. And let them not display [more of] their charms to any but 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 womenfolk, or those whom they rightfully possess, or such male attendants as are beyond all sexual desire, or children that are as yet unaware of women's nakedness; and let them not swing their legs [in walking] so as to draw attention to their hidden charms. And [always,] O you believers - all of you - turn unto God in repentance, so that you might attain to a happy state! 31 Marry off those who are single among you, and those of your male and female servants who are righteous. If they are poor, God will enrich them of His grace, for God is bounteous and all-knowing. 32 Those who cannot afford to marry should abstain from what is unlawful until God enriches them by His grace. And free those slaves you possess who wish to buy their freedom after a written undertaking, if you know they have some goodness, and give them out of the riches God has given you. Do not force your maids to prostitution if they wish to lead married lives, in order to get the benefits of this world. But if someone forces them, surely God (will forgive them) after their forced helplessness, for He is forgiving and kind. 33 We have already sent down to you verses making things clear, an illustration from (the story of) people who passed away before you, and an admonition for those who fear (Allah). 34
