33:53
O you who believe! (Do) not enter (the) houses (of) the Prophet except when permission is given to you for a meal, without awaiting its preparation. But when you are invited, then enter; and when you have eaten, then disperse and not seeking to remain for a conversation. Indeed, that was troubling the Prophet, and he is shy of (dismissing) you. But Allah not is shy of the truth. And when you ask them (for) anything then ask them from behind a screen. That (is) purer for your hearts and their hearts. And not is for you that you trouble (the) Messenger (of) Allah and not that you should marry his wives from after him, ever. Indeed, that is near Allah an enormity.
