The Verse of Al-Hijab (veiling of women) was revealed in connection with Zainab bint Jahsh.

حَدَّثَنَا خَلاَّدُ بْنُ يَحْيَى، حَدَّثَنَا عِيسَى بْنُ طَهْمَانَ، قَالَ سَمِعْتُ أَنَسَ بْنَ مَالِكٍ ـ رضى الله عنه ـ يَقُولُ نَزَلَتْ آيَةُ الْحِجَابِ فِي زَيْنَبَ بِنْتِ جَحْشٍ وَأَطْعَمَ عَلَيْهَا يَوْمَئِذٍ خُبْزًا وَلَحْمًا وَكَانَتْ تَفْخَرُ عَلَى نِسَاءِ النَّبِيِّ صلى الله عليه وسلم وَكَانَتْ تَقُولُ إِنَّ اللَّهَ أَنْكَحَنِي فِي السَّمَاءِ.
