The Marriage of Zainab Bint Jahsh, The Revelation of (the verse of) Hijab, and confirmation of the importance of the wedding feast.
حَدَّثَنَا أَبُو الرَّبِيعِ الزَّهْرَانِيُّ، وَأَبُو كَامِلٍ فُضَيْلُ بْنُ حُسَيْنٍ وَقُتَيْبَةُ بْنُ سَعِيدٍ قَالُوا حَدَّثَنَا حَمَّادٌ، - وَهُوَ ابْنُ زَيْدٍ - عَنْ ثَابِتٍ، عَنْ أَنَسٍ، - وَفِي رِوَايَةِ أَبِي كَامِلٍ سَمِعْتُ أَنَسًا، - قَالَ مَا رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم أَوْلَمَ عَلَى امْرَأَةٍ - وَقَالَ أَبُو كَامِلٍ عَلَى شَىْءٍ - مِنْ نِسَائِهِ مَا أَوْلَمَ عَلَى زَيْنَبَ فَإِنَّهُ ذَبَحَ شَاةً .
Anas (Allah be pleased with him) reported: I did not see Allah's Messenger (ﷺ) giving a wedding feast (on the marriage) of any one (of his wives) as he did in the case of (his marriage with) Zainab, for then he sacrificed a goat (on this occasion).
