O true believers, let your slaves and those among you who shall not have attained the age of puberty, ask leave of you, before they come into your presence, three times in the day; namely, before the morning prayer, and when ye lay aside your garments at noon, and after the evening prayer. These are the three times for you to be private: It shall be no crime in you, or in them, if they go into you without asking permission after these times, while ye are in frequent attendance, the one of you on the other. Thus God declareth his signs unto you; for God is knowing and wise.
