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 anything, or whether you conceal it, surely God has knowledge of everything. 54 It is no sin on them (the Prophet's wives, if they appear unveiled) before their fathers, or their sons, or their brothers, or their brother's sons, or the sons of their sisters, or their own (believing) women, or their (female) slaves, and keep your duty to Allah. Verily, Allah is Ever AllWitness over everything. 55 Allah and His angels send blessings on the Prophet: O ye that believe! Send ye blessings on him, and salute him with all respect. 56 Indeed, those who abuse Allah and His Messenger - Allah has cursed them in this world and the Hereafter and prepared for them a humiliating punishment. 57 Those who hurt believing men and believing women undeservedly, shall bear the guilt of slander and a major sin. 58
