O Ye who believe! enter not the houses of the Prophet, except when leave is given you, for a meal and at a time that ye will have to wait for its preparation; but when ye are invited, then enter, and when ye have eaten, then disperse, without lingering to enter into familiar discourse. Verily that incommodeth the Prophet, and he is shy of asking you to depart, bur Allah is not shy of the truth. And when ye ask of them aught, ask it of them from behind a curtain. That shall be purer for your hearts and for their hearts. And it is not lawful for you that ye should cause annoyance to the apostle of Allah, nor that ye should ever marry his wives after him; verily that in the sight of Allah shall be an enormity.
