"The Messenger of Allah ﷺ used to go to battle with Umm Sulaim, and other women with her, from the Ansar, who would give water and attend to the wounded." (Using translation from Tirmidhī 1575)  

«كَانَ النَّبِيُّ ﷺ يَغْزُو بِأُمِّ سُلَيْمٍ وَنِسْوَةٍ مَعَهَا مِنَ الْأَنْصَارِ يَسْقِينَ الْمَاءَ وَيُدَاوِينَ الْجَرْحَى»
