Sunan Ibn Majah, Book 6, Hadith 1560 (In-Book) ⓘ
It was narrated from Samurah bin Jundab Al-Fazari that the Messenger of Allah offered the funeral prayer for a woman who had died in Nifas,* and he stood level with her middle (i.e. her waist).”
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا أَبُو أُسَامَةَ، قَالَ الْحُسَيْنُ بْنُ ذَكْوَانَ أَخْبَرَنِي عَنْ عَبْدِ اللَّهِ بْنِ بُرَيْدَةَ الأَسْلَمِيِّ، عَنْ سَمُرَةَ بْنِ جُنْدُبٍ الْفَزَارِيِّ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ صَلَّى عَلَى امْرَأَةٍ مَاتَتْ فِي نِفَاسِهَا فَقَامَ وَسَطَهَا .
