Al-Ahzab 33:53 يا ايها الذين امنوا لا تدخلوا بيوت النبي الا ان يوذن لكم الى طعام غير ناظرين اناه ولاكن اذا دعيتم فادخلوا فاذا طعمتم فانتشروا ولا مستانسين لحديث ان ذالكم كان يوذي النبي فيستحيي منكم والله لا يستحيي من الحق واذا سالتموهن متاعا فاسالوهن من وراء حجاب ذالكم اطهر لقلوبكم وقلوبهن وما كان لكم ان توذوا رسول الله ولا ان تنكحوا ازواجه من بعده ابدا ان ذالكم كان عند الله عظيما ٥٣

O you who believe! Enter not the Prophet’s houses, unless permission is given to you for a meal, (and then) not (so early as) to wait for its preparation. But when you are invited, enter, and when you have taken your meal, disperse without sitting for a talk. Verily, such (behaviour) annoys the Prophet, and he is shy of (asking) you (to go); but Allâh is not shy of (telling you) the truth. And when you ask (his wives) for anything you want, ask them from behind a screen: that is purer for your hearts and for their hearts. And it is not (right) for you that you should annoy Allâh’s Messenger, nor that you should ever marry his wives after him (his death). Verily, with Allâh that shall be an enormity.
