(VII) You who believe, do not enter the Prophet's [private] quarters unless an invitation has been extended to you for a meal, though still without watching how it is prepared. However once you have been invited, then go on in; and once you have been fed, then disperse, not indulging in conversation. That has been disturbing the Prophet and he feels ashamed [to tell] you so. Yet God is not ashamed [to raise] the Truth. Whenever you ask (his wives) for any object, ask them for it from behind a curtain. That will be purer for your hearts as well as for their hearts. It is not proper for you to annoy God’s messenger, nor ever to marry his wives after him; that would be serious with God!
