باب رَدِّ النِّسَاءِ الْجَرْحَى وَالْقَتْلَى
Sahih al-Bukhari 2883

Narrated Ar-Rabi'bint Mu'auwidh:

We used to take part in holy battles with the Prophet (ﷺ) by providing the people with water and serving them and bringing the killed and the wounded back to Medina.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا بِشْرُ بْنُ الْمُفَضَّلِ، عَنْ خَالِدِ بْنِ ذَكْوَانَ، عَنِ الرُّبَيِّعِ بِنْتِ مُعَوِّذٍ، قَالَتْ كُنَّا نَغْزُو مَعَ النَّبِيِّ صلى الله عليه وسلم فَنَسْقِي الْقَوْمَ وَنَخْدُمُهُمْ، وَنَرُدُّ الْجَرْحَى وَالْقَتْلَى إِلَى الْمَدِينَةِ‏.‏
