Believers, let [even] those whom you rightfully possess, and those who are under age ask your leave on three occasions when they come in to see you: before the morning prayer, when you have taken off your garments in the heat of noon, and after the evening prayer. These are the three occasions for your privacy. At other times, there is nothing blameworthy if you or they go around visiting one another. Thus God makes clear to you His revelations: God is all knowing and wise.
