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 reveal anything or conceal it, verily Allah has full knowledge of all things. 54 It is no sin for them in respect to their fathers or their brothers, or their brothers sons, or their sisters sons, or their own women, or those whom their right hands own; and fear Allah; verily Allah is of everything ever a Witness. 55 Indeed, Allah confers blessing upon the Prophet, and His angels [ask Him to do so]. O you who have believed, ask [Allah to confer] blessing upon him and ask [Allah to grant him] peace. 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 And those who annoy the believing men and the believing women, without their earning it, shall surely bear the guilt of calumny and manifest sin. 58
