حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ اللَّهِ الرَّقَاشِيُّ، حَدَّثَنَا مُعْتَمِرُ بْنُ سُلَيْمَانَ، قَالَ سَمِعْتُ أَبِي يَقُولُ، حَدَّثَنَا أَبُو مِجْلَزٍ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ لَمَّا تَزَوَّجَ رَسُولُ اللَّهِ صلى الله عليه وسلم زَيْنَبَ ابْنَةَ جَحْشٍ دَعَا الْقَوْمَ، فَطَعِمُوا ثُمَّ جَلَسُوا يَتَحَدَّثُونَ وَإِذَا هُوَ كَأَنَّهُ يَتَهَيَّأُ لِلْقِيَامِ فَلَمْ يَقُومُوا، فَلَمَّا رَأَى ذَلِكَ قَامَ، فَلَمَّا قَامَ قَامَ مَنْ قَامَ، وَقَعَدَ ثَلاَثَةُ نَفَرٍ فَجَاءَ النَّبِيُّ صلى الله عليه وسلم لِيَدْخُلَ فَإِذَا الْقَوْمُ جُلُوسٌ ثُمَّ إِنَّهُمْ قَامُوا، فَانْطَلَقْتُ فَجِئْتُ فَأَخْبَرْتُ النَّبِيَّ صلى الله عليه وسلم أَنَّهُمْ قَدِ انْطَلَقُوا، فَجَاءَ حَتَّى دَخَلَ، فَذَهَبْتُ أَدْخُلُ فَأَلْقَى الْحِجَابَ بَيْنِي وَبَيْنَهُ فَأَنْزَلَ اللَّهُ ‏ {‏يَا أَيُّهَا الَّذِينَ آمَنُوا لاَ تَدْخُلُوا بُيُوتَ النَّبِيِّ‏} ‏ الآيَةَ

When Allah's Messenger (ﷺ) married Zainab bint Jahsh, he invited the people to a meal. They took the meal and remained sitting and talking. Then the Prophet (showed them) as if he is ready to get up, yet they did not get up. When he noticed that (there was no response to his movement), he got up, and the others too, got up except three persons who kept on sitting. The Prophet (ﷺ) came back in order to enter his house, but he went away again. Then they left, whereupon I set out and went to the Prophet (ﷺ) to tell him that they had departed, so he came and entered his house. I wanted to enter along with him, but he put a screen between me and him. Then Allah revealed: 'O you who believe! Do not enter the houses of the Prophet...' (33.53)
