24:27O you who believe! Do not enter homes other than your own, until you have asked permission and greeted their occupants. That is better for you, that you may be aware.

24:28And if you find no one in them, do not enter them until you are given permission. And if it is said to you, “Turn back,” then turn back. That is more proper for you. God is aware of what you do.

24:31And tell the believing women to restrain their looks, and to guard their privates, and not display their beauty except what is apparent thereof, and to draw their coverings over their breasts, and not expose their beauty except to their husbands, their fathers, their husbands' fathers, their sons, their husbands' sons, their brothers, their brothers' sons, their sisters' sons, their women, what their right hands possess, their male attendants who have no sexual desires, or children who are not yet aware of the nakedness of women. And they should not strike their feet to draw attention to their hidden beauty. And repent to God, all of you believers, so that you may succeed.
