КОРАН (английский перевод) - 33.53

Believers, do not enter the houses of the Prophet for a meal without waiting for the proper time, unless you are given permission. But if you are invited, enter, and when you have eaten, disperse, not desiring conversation, for that is hurtful to the Prophet and he would be shy before you; but of the truth Allah is not shy. And when you ask his wives for anything, speak to them from behind a curtain, that is cleaner for your hearts and theirs. You must not hurt the Messenger of Allah, nor shall you ever wed his wives after him, surely, this would be a monstrous thing with Allah.
