The offering of a funeral prayer for a woman who had died (or after) delivery and its (i.e., funeral prayer's) legal way of performing

Sahih al-Bukhari · Book 6 · Hadith 332

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.‏

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.
