Believers, do not enter the houses of the Prophet for a meal without permission. if you are invited, you may enter, but be punctual (so that you will not be waiting while the meal is being prepared). When you have finished eating, leave his home. Do not sit around chatting among yourselves. This will annoy the Prophet but he will feel embarrassed to tell you. God does not feel embarrassed to tell you the truth. When you want to ask something from the wives of the Prophet, ask them from behind the curtain. This would be more proper for you and for them. You are not supposed to trouble the Prophet or to ever marry his wives after his death, for this would be a grave offense in the sight of God. 53 If you do a thing openly or do it in secret, then surely Allah is Cognizant of all things. 54 It will not be an offense for the wives of the Prophet (not to observe the modest dress) in the presence of their fathers, sons, brothers, sons of their brothers and sisters, their own women, and their slave-girls. They should have fear of God. God witness all things. 55 Lo! Allah and His angels shower blessings on the Prophet. O ye who believe! Ask blessings on him and salute him with a worthy salutation. 56 Lo! those who malign Allah and His messenger, Allah hath cursed them in the world and the Hereafter, and hath prepared for them the doom of the disdained. 57 And as for those who malign believing men and believing women without their having done any wrong - they surely burden themselves with the guilt of calumny, and [thus] with a flagrant sin! 58
