The Verse of Al-Hijab (veiling of women) was revealed in connection with Zainab bint Jahsh. (On the day of her marriage with him) the Prophet ﷺ gave a wedding banquet with bread and meat; and she used to boast before other wives of the Prophet ﷺ and used to say, "Allah married me (to the Prophet ﷺ in the Heavens."  

سَمِعْتُ أَنَسَ بْنَ مَالِكٍ ؓ يَقُولُ نَزَلَتْ آيَةُ الْحِجَابِ فِي زَيْنَبَ بِنْتِ جَحْشٍ وَأَطْعَمَ عَلَيْهَا يَوْمَئِذٍ خُبْزًا وَلَحْمًا وَكَانَتْ تَفْخَرُ عَلَى نِسَاءِ النَّبِيِّ ﷺ وَكَانَتْ تَقُولُ إِنَّ اللَّهَ أَنْكَحَنِي فِي السَّمَاءِ  

Zainab bint Jahsh used to boast to the other wives of the Prophet and say: "Allah married me to him from above the Heavens." And the Verse of Hijab was revealed concerning her.  

سَمِعْتُ أَنَسَ بْنَ مَالِكٍ يَقُولُ كَانَتْ زَيْنَبُ بِنْتُ جَحْشٍ تَفْخَرُ عَلَى نِسَاءِ النَّبِيِّ ﷺ تَقُولُ إِنَّ اللَّهَ ﷻ أَنْكَحَنِي مِنَ السَّمَاءِ وَفِيهَا نَزَلَتْ آيَةُ الْحِجَابِ  

[Machine] I heard Anas ibn Malik say, "Zaynab bint Jahsh used to boast over the wives of the Prophet ﷺ, saying, 'Your fathers married you, but Allah married me from the heavens.'"  

سَمِعْتُ أَنَسَ بْنَ مَالِكٍ يَقُولُ كَانَتْ زَيْنَبُ بِنْتُ جَحْشٍ تَفْخَرُ عَلَى نِسَاءِ النَّبِيِّ ﷺ تَقُولُ «زَوَّجَكُنَّ آبَاؤُكُنَّ وَاللهُ أَنْكَحَنِي مِنَ السَّمَاءِ»  

Zainab bint Jahsh used to boast to the other wives of the Prophet and say: "Allah married me to him from above the Heavens." And the Verse of Hijab was revealed concerning her. (Using translation from Nasāʾī 3252)   

سَمِعْتُ أَنَسًا يَقُولُ كَانَتْ زَيْنَبُ تَفْخَرُ عَلَى نِسَاءِ النَّبِيِّ ﷺ إِنَّ اللهَ أَنْكَحَنِي مِنَ السَّمَاءِ وَفِيهَا نَزَلَتْ آيَةُ الْحِجَابِ  

[Machine] I heard Anas saying, "Zaynab used to boast among the wives of the Prophet ﷺ that Allah married me from the heavens and in it, the verse of Hijab was revealed."  

سَمِعْتُ أَنَسًا يَقُولُ «كَانَتْ زَيْنَبُ تَفْتَخِرُ عَلَى نِسَاءِ النَّبِيِّ ﷺ أَنَّ اللهَ أَنْكَحَنِي مِنَ السَّمَاءِ وَفِيهَا نَزَلَتْ آيَةُ الْحِجَابِ»
