When Messenger of Allah ﷺ married Zainab bint Jahsh, he made the people eat meat and bread to their fill (by giving a Walima banquet). Then he went out to the dwelling places of the mothers of the believers (his wives), as he used to do in the morning of his marriage. He would greet them and invoke good on them, and they (too) would return his greeting and invoke good on him. When he returned to his house, he found two men talking to each other; and when he saw them, he went out of his house again. When those two men saw Messenger of Allah ﷺ: going out of his house, they quickly got up (and departed). I do not remember whether I informed him of their departure, or he was informed (by somebody else). So he returned, and when he entered the house, he lowered the curtain between me and him. Then the Verse of Al-Hijab was revealed.  

أَوْلَمَ رَسُولُ اللَّهِ ﷺ حِينَ بَنَى بِزَيْنَبَ ابْنَةِ جَحْشٍ فَأَشْبَعَ النَّاسَ خُبْزًا وَلَحْمًا ثُمَّ خَرَجَ إِلَى حُجَرِ أُمَّهَاتِ الْمُؤْمِنِينَ كَمَا كَانَ يَصْنَعُ صَبِيحَةَ بِنَائِهِ فَيُسَلِّمُ عَلَيْهِنَّ وَيَدْعُو لَهُنَّ وَيُسَلِّمْنَ عَلَيْهِ وَيَدْعُونَ لَهُ فَلَمَّا رَجَعَ إِلَى بَيْتِهِ رَأَى رَجُلَيْنِ جَرَى بِهِمَا الْحَدِيثُ فَلَمَّا رَآهُمَا رَجَعَ عَنْ بَيْتِهِ فَلَمَّا رَأَى الرَّجُلاَنِ نَبِيَّ اللَّهِ ﷺ رَجَعَ عَنْ بَيْتِهِ وَثَبَا مُسْرِعَيْنِ فَمَا أَدْرِي أَنَا أَخْبَرْتُهُ بِخُرُوجِهِمَا أَمْ أُخْبِرَ فَرَجَعَ حَتَّى دَخَلَ الْبَيْتَ وَأَرْخَى السِّتْرَ بَيْنِي وَبَيْنَهُ وَأُنْزِلَتْ آيَةُ الْحِجَابِ وَقَالَ ابْنُ أَبِي مَرْيَمَ أَخْبَرَنَا يَحْيَى حَدَّثَنِي حُمَيْدٌ سَمِعَ أَنَسًا عَنِ النَّبِيِّ ﷺ  

[Machine] Did not the Messenger of Allah, ﷺ , call for Zainab and feed the Muslims with bread and meat, then he left as he used to do when he got married, and he visited the Mothers of the Believers and greeted them and prayed for them, and they also greeted him and prayed for him. Then he returned with me, and when he reached the door, he saw two men talking near the wall of the house. When the Messenger of Allah, ﷺ , saw them, he turned around and when the two men saw the Prophet, they hastily went out. I do not know whether I informed him or if someone else informed him, but the Prophet, ﷺ , returned.  

أَوْلَمَ رَسُولُ اللهِ ﷺ بِزَيْنَبَ فَأَشْبَعَ الْمُسْلِمِينَ خُبْزًا وَلَحْمًا ثُمَّ خَرَجَ كَمَا كَانَ يَصْنَعُ إِذَا تَزَوَّجَ فَيَأْتِي حُجَرَ أُمَّهَاتِ الْمُؤْمِنِينَ فَيُسَلِّمُ عَلَيْهِنَّ وَيَدْعُو لَهُنَّ وَيُسَلِّمْنَ عَلَيْهِ وَيَدْعُونَ لَهُ ثُمَّ رَجَعَ وَأَنَا مَعَهُ فَلَمَّا انْتَهَى إِلَى الْبَابِ إِذَا رَجُلَانِ قَدْ جَرَى بَيْنَهُمَا الْحَدِيثُ فِي نَاحِيَةِ الْبَيْتِ فَلَمَّا أَبْصَرَهُمَا رَسُولُ اللهِ ﷺ انْصَرَفَ فَلَمَّا رَأَى الرَّجُلَانِ النَّبِيَّ ﷺ قَدْ رَجَعَ وَثَبَا فَزِعَيْنِ فَخَرَجَا فَلَا أَدْرِي أَنَا أَخْبَرْتُهُ أَوْ مَنْ أَخْبَرَهُ فَرَجَعَ النَّبِيُّﷺ  

[Machine] I invited the Muslims to the feast of the Messenger of Allah ﷺ in the morning, hosted by Bana Bint Jahsh. He fed the Muslims bread and meat. Then, he returned as he used to do and greeted his wives, and they said hello to him. Then, he returned to his house with me. When he reached the house, he saw two men talking near the house. When he saw them, he turned back. When the two men saw the Prophet ﷺ leaving his house, they hurried towards him. I don't know if I informed him or he was informed about them, so he returned to his house and put a curtain between him and me. Then, the verse of hijab was revealed.  

دَعَوْتُ الْمُسْلِمِينَ إِلَى وَلِيمَةِ رَسُولِ اللهِ ﷺ صَبِيحَةَ بَنَى بِزَيْنَبَ بِنْتِ جَحْشٍ فَأَشْبَعَ الْمُسْلِمِينَ خُبْزًا وَلَحْمًا قَالَ ثُمَّ رَجَعَ كَمَا كَانَ يَصْنَعُ فَأَتَى حُجَرَ نِسَائِهِ فَسَلَّمَ عَلَيْهِنَّ فَدَعَوْنَ لَهُ قَالَ ثُمَّ رَجَعَ إِلَى بَيْتِهِ وَأَنَا مَعَهُ فَلَمَّا انْتَهَى إِلَى الْبَيْتِ فَإِذَا رَجُلَانِ قَدْ جَرَى بَيْنَهُمَا الْحَدِيثُ فِي نَاحِيَةِ الْبَيْتِ فَلَمَّا بَصَرَ بِهِمَا وَلَّى رَاجِعًا فَلَمَّا رَأَى الرَّجُلَانِ النَّبِيَّ ﷺ قَدْ وَلَّى عَنْ بَيْتِهِ قَامَا مُسْرِعَيْنِ فَلَا أَدْرِي أَنَا أَخْبَرْتُهُ أَوْ أُخْبِرَ بِهِ فَرَجَعَ إِلَى مَنْزِلِهِ وَأَرْخَى السِّتْرَ بَيْنَهُ وَبَيْنِي وَأُنْزِلَتْ آيَةُ الْحِجَابِ
