(VIII) You who believe, have those whom your right hands control and those of you who have not yet reached puberty, ask permission from you on three occasions: before the daybreak prayer; when you take off your clothes at noon [for a siesta]; and after the late evening prayer. You have three times for privacy. There is no objection for you nor for them outside those times as they move around you so some of you may wait on others. Thus God explains signs to you; God is Aware, Wise.
