O ye who believe! do not enter the houses of the prophet, unless leave be given you, for a meal,- not watching till it is cooked! But when ye are invited, then enter; and when ye have fed, disperse, not engaging in familiar discourse. Verily, that would annoy the prophet and he would be ashamed for your sake, but God is not ashamed of the truth. And when ye ask them for an article, ask them from behind a curtain; that is purer for your hearts and for theirs. It is not right for you to annoy the prophet of God, nor to wed his wives after him ever; verily, that is with God a serious thing.
