It was narrated that Samurah said:

"I offered the funeral prayer with the Messenger of Allah ﷺ for Umm Ka'b who had died during childbirth, and during the prayer, the Messenger of Allah ﷺ stood at her middle."

أَخْبَرَنَا حُمَيْدُ بْنُ مَسْعَدَةَ، عَنْ عَبْدِ الْوَارِثِ، عَنْ حُسَيْنٍ، - يَعْنِي الْمُعَلِّمَ - عَنِ ابْنِ بُرَيْدَةَ، عَنْ سَمُرَةَ، قَالَ صَلَّيْتُ مَعَ رَسُولِ اللَّهِ ﷺ عَلَى أُمِّ كَعْبٍ مَاتَتْ فِي نِفَاسِهَا فَقَامَ رَسُولُ اللَّهِ ﷺ فِي الصَّلاَةِ فِي وَسَطِهَا .
