Believers, do not enter other people's houses until you have asked their owners' permission and greeted them. That will be the better for you, so that you may be heedful. 27 Hence, [even] if you find no one within [the house,] do not enter it until you are given leave; and if you are told, "Turn back," then turn back. This will be most conducive to your purity; and God has full knowledge of all that you do. 28 There is no sin on you that you enter (without taking permission) houses uninhabited (i.e. not possessed by anybody), (when) you have any interest in them. And Allah has knowledge of what you reveal and what you conceal. 29 Say to the believers they should lower their gaze and guard their private parts that is purer for them. Allah is Aware of the things they do. 30 And tell the believing women to reduce [some] of their vision and guard their private parts and not expose their adornment except that which [necessarily] appears thereof and to wrap [a portion of] their headcovers over their chests and not expose their adornment except to their husbands, their fathers, their husbands' fathers, their sons, their husbands' sons, their brothers, their brothers' sons, their sisters' sons, their women, that which their right hands possess, or those male attendants having no physical desire, or children who are not yet aware of the private aspects of women. And let them not stamp their feet to make known what they conceal of their adornment. And turn to Allah in repentance, all of you, O believers, that you might succeed. 31 And marry those among you who are single (i.e. a man who has no wife and the woman who has no husband) and (also marry) the Salihun (pious, fit and capable ones) of your (male) slaves and maid-servants (female slaves). If they be poor, Allah will enrich them out of His Bounty. And Allah is All-Sufficent for His creatures' needs, All-Knowing (about the state of the people). 32 Let those who cannot find someone to marry maintain chastity until God makes them rich through His favors. Let the slaves who want to buy their freedom have an agreement with you in writing if you find them to be virtuous. Give them money out of God's property which He has given to you. Do not force your girls into prostitution to make money if they want to be chaste. If they have been compelled to do so, God will be All-merciful and All-forgiving to them. 33 And indeed We have sent down towards you clear verses, and some account of those who preceded you, and advice for the pious. 34
