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
