33.53 . O ye who believe! Enter not the dwellings of the Prophet for a meal without waiting for the proper time , unless permission be granted you . But if ye are invited , enter , and , when , your meal is ended , then disperse . Linger not for conversation . Lo! that would cause annoyance to the Prophet , and he would be shy of ( asking ) you ( to go ) ; but Allah is not shy of the truth . And when ye ask of them ( the wives of the Prophet ) anything , ask it of them from behind a curtain . That is purer for your hearts and for their hearts . And it is not for you to cause annoyance to the messenger of Allah , nor that ye should ever marry his wives after him . Lo! that in Allah ' s sight would be an enormity .
