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 Whether ye disclose a thing or conceal it, verily Allah is of everything ever Knower. 54 There is no harm if they come before their fathers or their sons, or their brothers and their brothers' and sisters' sons, or their women folk or captive maids they possess. Follow the commands of God. Verily God is witness to everything. 55 Surely Allah and His angels bless the Prophet; O you who believe! call for (Divine) blessings on him and salute him with a (becoming) salutation. 56 Those who annoy Allah and His Messenger - Allah has cursed them in this World and in the Hereafter, and has prepared for them a humiliating Punishment. 57 Those who affront believing men and believing women without their having deserved it [done any wrong] shall bear the weight of slander and flagrant sin. 58
