Sunan an-Nasa'i 393
أَخْبَرَنَا حُمَيْدُ بْنُ مَسْعَدَةَ، عَنْ عَبْدِ الْوَارِثِ، عَنْ حُسَيْنٍ، - يَعْنِي الْمُعَلِّمَ - عَنِ ابْنِ بُرَيْدَةَ، عَنْ سَمُرَةَ، قَالَ صَلَّيْتُ مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم عَلَى أُمِّ كَعْبٍ مَاتَتْ فِي نِفَاسِهَا فَقَامَ رَسُولُ اللَّهِ صلى الله عليه وسلم فِي الصَّلاَةِ فِي وَسَطِهَا .
Humayd ibn Mas'adah narrated to us, from 'Abd al-Warith, from Husayn—that is, al-Mu'allim—from Ibn Buraydah, from Samurah, who said: I prayed with the Messenger of Allah (ﷺ) over Umm Ka'b, who died during her postpartum bleeding. During the funeral prayer, the Messenger of Allah (ﷺ) stood at the middle of her body.
Translation notes
The Arabic chain includes the identification of Husayn as al-Mu'allim; the English witness omits the chain.
أَخْبَرَنَا حُمَيْدُ بْنُ مَسْعَدَةَ،
The English witness omits the Arabic chain and narrator identification.
Please verify the chain and Husayn's identification against the Arabic source.
