The believers hereby are forbidden to enter the houses of the Prophet without permission and are not supposed to delay their stay hoping to be fed. Enter, if you are invited. Eat, if you are offered and leave immediately. Do not bother the Prophet with lengthy discussions; he is shy asking you to leave but God is not shy in bringing to your attention [theses etiquettes.] If you have to talk to the wives of the Prophet, do not talk face to face; talk from behind a curtain. This is better for the purity of your hearts as well as theirs. You should not do/say anything to hurt the Prophet of God. You should also not [as a sign of respect] marry any of the wives of the Prophet after him [as you are not supposed to marry your fathers’ wives after his death out of respect]; this is a great sin in the sight of God.
