33:49O you who believe! When you marry believing women, but then divorce them before you have touched them, there is no waiting period for you to observe in respect to them; but compensate them, and release them in a graceful manner.

33:50O Prophet! We have permitted to you your wives to whom you have given their dowries, and those you already have, as granted to you by God, and the daughters of your paternal uncle, and the daughters of your paternal aunts, and the daughters of your maternal uncle, and the daughters of your maternal aunts who emigrated with you, and a believing woman who has offered herself to the Prophet, if the Prophet desires to marry her, exclusively for you, and not for the believers. We know what We have ordained for them regarding their wives and those their right-hands possess. This is to spare you any difficulty. God is Forgiving and Merciful.

33:53O you who believe! Do not enter the homes of the Prophet, unless you are given permission to come for a meal; and do not wait for its preparation. And when you are invited, go in. And when you have eaten, disperse, without lingering for conversation. This irritates the Prophet, and he shies away from you, but God does not shy away from the truth. And when you ask his wives for something, ask them from behind a screen; that is purer for your hearts and their hearts. You must never offend the Messenger of God, nor must you ever marry his wives after him, for that would be an enormity with God.
