Believers, let those your right hand owns and those who have not come of age ask permission of you three times before the dawn prayer, when you put aside your garments, in the heat of noon, and after the night prayer. These are the three occasions of privacy. There is no fault in you or them, apart from these, that they go about you, you are of each other. As such Allah makes plain to you His verses, Allah is the Knower, the Wise.
