[Machine] Zainab bint Jahsh used to boast over the wives of the Prophet ﷺ, saying, "Indeed, Allah married me from the sky and provided me with bread and meat on that day, while the people were sitting just as they are now in this house." Then, the Messenger of Allah ﷺ stood up and left, staying away for as long as Allah willed, and then he returned while the people were still sitting just as they were. This troubled him and it became known on his face, and that is when the verse of hijab was revealed.  

كَانَتْ زَيْنَبُ بِنْتُ جَحْشٍ تَفْخَرُ عَلَى نِسَاءِ النَّبِيِّ ﷺ تَقُولُ إِنَّ اللهَ أَنْكَحَنِي مِنَ السَّمَاءِ وَأَطْعَمَ عَلَيْهَا يَوْمَئِذٍخُبْزًا وَلَحْمًا وَكَانَ الْقَوْمُ جُلُوسًا كَمَا هُمْ فِي الْبَيْتِ فَقَامَ رَسُولُ اللهِ ﷺ فَخَرَجَ فَلَبِثَ مَا شَاءَ اللهُ أَنْ يَلْبَثَ ثُمَّ رَجَعَ وَالْقَوْمُ جُلُوسٌ كَمَا هُمْ فَشَقَّ ذَلِكَ عَلَيْهِ وَعُرِفَ فِي وَجْهِهِ فَنَزَلَتْ آيَةُ الْحِجَابِ
