(48) باب النِّسَاءُ الْغَازِيَاتُ يُرْضَخُ لَهُنَّ وَلاَ يُسْهَمُ وَالنَّهْىُ عَنْ قَتْلِ صِبْيَانِ أَهْلِ الْحَرْبِ
It has been narrated on the authority of Umm 'Atiyya, the Ansarite, who said:
I took part with the Messenger of Allah (ﷺ) in seven battles. I would stay behind in the camp of men, cook their food, treat the wounded and nurse the sick.
