Hadith 13478

(حديث مرفوع) حَدَّثَنَا يَعْقُوبُ ، حَدَّثَنَا أَبِي ، عَنْ صَالِحٍ ، قَالَ ابْنُ شِهَابٍ : إِنَّ أَنَسَ بْنَ مَالِكٍ ، قَالَ : أَنَا أَعْلَمُ النَّاسِ بِالْحِجَابِ ، لَقَدْ كَانَ أُبَيُّ بْنُ كَعْبٍ يَسْأَلُنِي عَنْهُ ، قَالَ أَنَسٌ : " أَصْبَحَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عَرُوسًا بِزَيْنَبَ ابْنَةِ جَحْشٍ ، قَالَ : قَالَ : وَكَانَ تَزَوَّجَهَا بِالْمَدِينَةِ ، فَدَعَا النَّاسَ لِلطَّعَامِ بَعْدَ ارْتِفَاعِ النَّهَارِ ، فَجَلَسَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، وَجَلَسَ مَعَهُ رِجَالٌ بَعْدَمَا قَامَ الْقَوْمُ ، حَتَّى قَامَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ، فَمَشَى وَمَشَيْتُ مَعَهُ حَتَّى بَلَغَ حُجْرَةَ عَائِشَةَ ، ثُمَّ ظَنَّ أَنَّهُمْ قَدْ خَرَجُوا ، فَرَجَعَ وَرَجَعْتُ مَعَهُ ، قَالَ : فَإِذَا هُمْ جُلُوسٌ مَكَانَهُمْ ، فَرَجَعَ وَرَجَعْتُ مَعَهُ الثَّانِيَةَ ، حَتَّى بَلَغَ حُجْرَةَ عَائِشَةَ فَرَجَعَ وَرَجَعْتُ مَعَهُ ، فَإِذَا هُمْ قَدْ قَامُوا ، فَضَرَبَ بَيْنِي وَبَيْنَهُ بِالسِّتْرِ ، وَأُنْزِلَ الْحِجَابُ " .
It is narrated from Hazrat Anas (may Allah be pleased with him) that when the command of veiling (purdah) was revealed, I know the circumstances of that time better than anyone else. That night, the Prophet (peace and blessings be upon him) was in seclusion with Hazrat Zainab (may Allah be pleased with her), and in the morning the Prophet (peace and blessings be upon him) was a bridegroom. After that, the Prophet (peace and blessings be upon him) invited the people, they came, ate food, and left, but some people remained sitting there and continued to sit for quite a while, until the Prophet (peace and blessings be upon him) himself got up and went outside. I also went outside so that they might leave as well. The Prophet (peace and blessings be upon him) and I, while walking, stopped at the threshold of Hazrat Aisha’s (may Allah be pleased with her) chamber. The Prophet (peace and blessings be upon him) thought that perhaps those people had now left, so the Prophet (peace and blessings be upon him) returned, and I was with him, but those people were still sitting there. The same thing happened again, but this time those people had actually left. Then the Prophet (peace and blessings be upon him) entered inside and hung a curtain, and Allah revealed the verse of hijab.
