Believers! Let those whom you rightfully possess, and those of you who have not yet attained to puberty, ask leave of you at three times of day: before the prayer of daybreak, and whenever you lay aside your garments in the middle of the day, and after the prayer of nightfall. These are three occasions on which you may happen to be undressed. Beyond these occasions, neither you nor they will incur any sin if they move freely about you, attending to one another. Thus God makes clear to you His revelations. God is all-knowing, wise.
