يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ لَا تَدْخُلُوا۟ بُيُوتَ ٱلنَّبِىِّ إِلَّآ أَن يُؤْذَنَ لَكُمْ إِلَىٰ طَعَامٍ غَيْرَ نَٰظِرِينَ إِنَىٰهُ وَلَٰكِنْ إِذَا دُعِيتُمْ فَٱدْخُلُوا۟ فَإِذَا طَعِمْتُمْ فَٱنتَشِرُوا۟ وَلَا مُسْتَـْٔنِسِينَ لِحَدِيثٍ ۚ إِنَّ ذَٰلِكُمْ كَانَ يُؤْذِى ٱلنَّبِىَّ فَيَسْتَحْىِۦ مِنكُمْ ۖ وَٱللَّهُ لَا يَسْتَحْىِۦ مِنَ ٱلْحَقِّ ۚ وَإِذَا سَأَلْتُمُوهُنَّ مَتَٰعًۭا فَسْـَٔلُوهُنَّ مِن وَرَآءِ حِجَابٍۢ ۚ ذَٰلِكُمْ أَطْهَرُ لِقُلُوبِكُمْ وَقُلُوبِهِنَّ ۚ وَمَا كَانَ لَكُمْ أَن تُؤْذُوا۟ رَسُولَ ٱللَّهِ وَلَآ أَن تَنكِحُوٓا۟ أَزْوَٰجَهُۥ مِنۢ بَعْدِهِۦٓ أَبَدًا ۚ إِنَّ ذَٰلِكُمْ كَانَ عِندَ ٱللَّهِ عَظِيمًا
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.
