Narrated by:Anas bin Malik said
It was narrated that Anas bin Malik said:“I never saw the Messenger of Allah give a wedding feast for any of his wives like the feast he gave for Zainab, for which he slaughtered a sheep.”
حَدَّثَنَا أَحْمَدُ بْنُ عَبْدَةَ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ ثَابِتٍ الْبُنَانِيِّ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ مَا رَأَيْتُ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ أَوْلَمَ عَلَى شَىْءٍ مِنْ نِسَائِهِ مَا أَوْلَمَ عَلَى زَيْنَبَ فَإِنَّهُ ذَبَحَ شَاةً .
