Sahih al-Bukhari 6271
Narrated Anas bin Malik:
When Allah's Messenger (ﷺ) married Zainab bint Jahsh, he invited the people who took their meals and then 
remained sitting and talking. The Prophet (ﷺ) pretended to be ready to get up, but the people did not get 
up. When he noticed that, he got up, and when he had got up, some of those people got up along with 
him and there remained three (who kept on sitting). Then the Prophet (ﷺ) came back and found those 
people still sitting. Later on those people got up and went away. So I went to the Prophet (ﷺ) and 
informed him that they had left. 
The Prophet (ﷺ) came, and entered (his house). I wanted to enter(along with him) but he dropped a curtain 
between me and him. Allah then revealed: 'O you who believe! Do not enter the Prophet's Houses 
until leave is given... (to His statement)... Verily! That shall be an enormity, in Allah's sight.' (33.53)
حَدَّثَنَا الْحَسَنُ بْنُ عُمَرَ، حَدَّثَنَا مُعْتَمِرٌ، سَمِعْتُ أَبِي يَذْكُرُ، عَنْ أَبِي مِجْلَزٍ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ لَمَّا تَزَوَّجَ رَسُولُ اللَّهِ صلى الله عليه وسلم زَيْنَبَ ابْنَةَ جَحْشٍ دَعَا النَّاسَ طَعِمُوا ثُمَّ جَلَسُوا يَتَحَدَّثُونَ ـ قَالَ ـ فَأَخَذَ كَأَنَّهُ يَتَهَيَّأُ لِلْقِيَامِ فَلَمْ يَقُومُوا، فَلَمَّا رَأَى ذَلِكَ قَامَ، فَلَمَّا قَامَ قَامَ مَنْ قَامَ مَعَهُ مِنَ النَّاسِ، وَبَقِيَ ثَلاَثَةٌ، وَإِنَّ النَّبِيَّ صلى الله عليه وسلم جَاءَ لِيَدْخُلَ فَإِذَا الْقَوْمُ جُلُوسٌ، ثُمَّ إِنَّهُمْ قَامُوا فَانْطَلَقُوا ـ قَالَ ـ فَجِئْتُ فَأَخْبَرْتُ النَّبِيَّ صلى الله عليه وسلم أَنَّهُمْ قَدِ انْطَلَقُوا، فَجَاءَ حَتَّى دَخَلَ فَذَهَبْتُ أَدْخُلُ، فَأَرْخَى الْحِجَابَ بَيْنِي وَبَيْنَهُ، وَأَنْزَلَ اللَّهُ تَعَالَى ‏{‏يَا أَيُّهَا الَّذِينَ آمَنُوا لاَ تَدْخُلُوا بُيُوتَ النَّبِيِّ إِلاَّ أَنْ يُؤْذَنَ لَكُمْ‏}‏ إِلَى قَوْلِهِ ‏{‏إِنَّ ذَلِكُمْ كَانَ عِنْدَ اللَّهِ عَظِيمًا‏}‏‏.‏
