Surah Al-Ahzab, ayah 53

33:53

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَدۡخُلُواْ بُيُوتَ ٱلنَّبِيِّ إِلَّآ أَن يُؤۡذَنَ لَكُمۡ إِلَىٰ طَعَامٍ غَيۡرَ نَٰظِرِينَ إِنَىٰهُ وَلَٰكِنۡ إِذَا دُعِيتُمۡ فَٱدۡخُلُواْ فَإِذَا طَعِمۡتُمۡ فَٱنتَشِرُواْ وَلَا مُسۡتَـٔۡنِسِينَ لِحَدِيثٍۚ إِنَّ ذَٰلِكُمۡ كَانَ يُؤۡذِي ٱلنَّبِيَّ فَيَسۡتَحۡيِۦ مِنكُمۡۖ وَٱللَّهُ لَا يَسۡتَحۡيِۦ مِنَ ٱلۡحَقِّۚ وَإِذَا سَأَلۡتُمُوهُنَّ مَتَٰعٗا فَسۡـَٔلُوهُنَّ مِن وَرَآءِ حِجَابٖۚ ذَٰلِكُمۡ أَطۡهَرُ لِقُلُوبِكُمۡ وَقُلُوبِهِنَّۚ وَمَا كَانَ لَكُمۡ أَن تُؤۡذُواْ رَسُولَ ٱللَّهِ وَلَآ أَن تَنكِحُوٓاْ أَزۡوَٰجَهُۥ مِنۢ بَعۡدِهِۦٓ أَبَدًاۚ إِنَّ ذَٰلِكُمۡ كَانَ عِندَ ٱللَّهِ عَظِيمًا ٥٣

O you who have believed, do not enter the houses of the Prophet except when you are permitted for a meal, without awaiting its readiness. But when you are invited, then enter; and when you have eaten, disperse without seeking to remain for conversation. Indeed, that [behavior] was troubling the Prophet, and he is shy of [dismissing] you. But Allāh is not shy of the truth. And when you ask [his wives] for something, ask them from behind a partition. That is purer for your hearts and their hearts. And it is not [conceivable or lawful] for you to harm the Messenger of Allāh or to marry his wives after him, ever. Indeed, that would be in the sight of Allāh an enormity.
