The Book of Prayer - Funerals
حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، أَخْبَرَنَا أَسْبَاطٌ، حَدَّثَنَا هِشَامٌ، عَنْ حَفْصَةَ، عَنْ أُمِّ عَطِيَّةَ، قَالَتْ أَخَذَ عَلَيْنَا رَسُولُ اللَّهِ صلى الله عليه وسلم فِي الْبَيْعَةِ أَلاَّ تَنُحْنَ فَمَا وَفَتْ مِنَّا غَيْرُ خَمْسٍ مِنْهُنَّ أُمُّ سُلَيْمٍ .Umm 'Atiyya reported that the Messenger of Allah (ﷺ) took pledge from us (including this promise) that we would not lament. Only five amongst us fulfilled the promise, and one of them (who fulfilled the promise) was Umm Sulaim
From Sahih Muslim, whose reports the scholars accept as authentic.
