Believers, enter not the houses of the Prophet without his permission, nor wait for a meal to be prepared; instead enter when you are invited to eat, and when you have had the meal, disperse. Do not linger in idle talk. That is hurtful to the Prophet but he does not express it out of shyness; but Allah is not ashamed of speaking out the Truth. And if you were to ask the wives of the Prophet for something, ask from behind a curtain. That is more apt for the cleanness of your hearts and theirs. It is not lawful for you to cause hurt to Allah's Messenger, nor to ever marry his wives after him. Surely that would be an enormous sin in Allah's sight. 53 Whether you reveal a thing or conceal it, indeed Allah is ever, of all things, Knowing. 54 There is no blame on them in respect of their fathers, nor their brothers, nor their brothers' sons, nor their sisters' sons nor their own women, nor of what their right hands possess; and be careful of (your duty to) Allah; surely Allah is a witness of all things. 55 Verily, God and His angels bless the Prophet: [hence,] O you who have attained to faith, bless him and give yourselves up [to his guidance] in utter self-surrender! 56 Verily those who cause annoyance to Allah and His Messenger - Allah has cursed them in this world and in the Hereafter and has prepared for them a humiliating chastisement. 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
