باب الصَّلاَةِ عَلَى النُّفَسَاءِ وَسُنَّتِهَا
Sahih al-Bukhari 332

Narrated Samura bin Jundub:

The Prophet (ﷺ) offered the funeral prayer for the dead body of a woman who died during delivery (i.e. childbirth) and he stood by the middle of her body.

حَدَّثَنَا أَحْمَدُ بْنُ أَبِي سُرَيْجٍ، قَالَ أَخْبَرَنَا شَبَابَةُ، قَالَ أَخْبَرَنَا شُعْبَةُ، عَنْ حُسَيْنٍ الْمُعَلِّمِ، عَنِ ابْنِ بُرَيْدَةَ، عَنْ سَمُرَةَ بْنِ جُنْدُبٍ، أَنَّ امْرَأَةً، مَاتَتْ فِي بَطْنٍ، فَصَلَّى عَلَيْهَا النَّبِيُّ صلى الله عليه وسلم فَقَامَ وَسَطَهَا‏.‏
