I was ten years old when Messenger of Allah ﷺ arrived at Medina. My mother and aunts used to urge me to serve the Prophet ﷺ regularly, and I served him for ten years. When the Prophet ﷺ died I was twenty years old, and I knew about the order of Al-Hijab (veiling of ladies) more than any other person when it was revealed. It was revealed for the first time when Messenger of Allah ﷺ had consummated his marriage with Zainab bint Jahsh. When the day dawned, the Prophet ﷺ was a bridegroom and he invited the people to a banquet, so they came, ate, and then all left except a few who remained with the Prophet ﷺ for a long time. The Prophet ﷺ got up and went out, and I too went out with him so that those people might leave too. The Prophet ﷺ proceeded and so did I, till he came to the threshold of ʿAisha's dwelling place. Then thinking that these people have left by then, he returned and so did I along with him till he entered upon Zainab and behold, they were still sitting and had not gone. So the Prophet ﷺ again went away and I went away along with him. When we reached the threshold of ʿAisha's dwelling place, he thought that they had left, and so he returned and I too, returned along with him and found those people had left. Then the Prophet ﷺ drew a curtain between me and him, and the Verses of Al-Hijab were revealed.  

أَنَّهُ كَانَ ابْنَ عَشْرِ سِنِينَ مَقْدَمَ رَسُولِ اللَّهِ ﷺ الْمَدِينَةَ فَكَانَ أُمَّهَاتِي يُوَاظِبْنَنِي عَلَى خِدْمَةِ النَّبِيِّ ﷺ فَخَدَمْتُهُ عَشْرَ سِنِينَ وَتُوُفِّيَ النَّبِيُّ ﷺ وَأَنَا ابْنُ عِشْرِينَ سَنَةً فَكُنْتُ أَعْلَمَ النَّاسِ بِشَأْنِ الْحِجَابِ حِينَ أُنْزِلَ وَكَانَ أَوَّلَ مَا أُنْزِلَ فِي مُبْتَنَى رَسُولِ اللَّهِ ﷺ بِزَيْنَبَ ابْنَةِ جَحْشٍ أَصْبَحَ النَّبِيُّ ﷺ بِهَا عَرُوسًا فَدَعَا الْقَوْمَ فَأَصَابُوا مِنَ الطَّعَامِ ثُمَّ خَرَجُوا وَبَقِيَ رَهْطٌ مِنْهُمْ عِنْدَ النَّبِيِّ ﷺ فَأَطَالُوا الْمُكْثَ فَقَامَ النَّبِيُّ ﷺ فَخَرَجَ وَخَرَجْتُ مَعَهُ لِكَىْ يَخْرُجُوا فَمَشَى النَّبِيُّ ﷺ وَمَشَيْتُ حَتَّى جَاءَ عَتَبَةَ حُجْرَةِ عَائِشَةَ ثُمَّ ظَنَّ أَنَّهُمْ خَرَجُوا فَرَجَعَ وَرَجَعْتُ مَعَهُ حَتَّى إِذَا دَخَلَ عَلَى زَيْنَبَ فَإِذَا هُمْ جُلُوسٌ لَمْ يَقُومُوا فَرَجَعَ النَّبِيُّ ﷺ وَرَجَعْتُ مَعَهُ حَتَّى إِذَا بَلَغَ عَتَبَةَ حُجْرَةِ عَائِشَةَ وَظَنَّ أَنَّهُمْ خَرَجُوا فَرَجَعَ وَرَجَعْتُ مَعَهُ فَإِذَا هُمْ قَدْ خَرَجُوا فَضَرَبَ النَّبِيُّ ﷺ بَيْنِي وَبَيْنَهُ بِالسِّتْرِ وَأُنْزِلَ الْحِجَابُ
