Believers, let your slaves and those who are under age ask your leave on three occasions when they come in to see you: before the dawn prayer, when you have put off your garments in the heat of noon, and after the evening prayer. These are the three occasions when none may intrude upon your privacy. At other times, it shall be no offence for you, or them, to go around visiting one another. Thus God makes plain to you His revelations: God is all-knowing and wise.
