It has been narrated on the authority of Anas b. Malik who said that the Messenger of Allah ﷺ allowed Umm Sulaim and some other women of the Ansar to accompany him when he went to war; they would give water (to the soldiers) and would treat the wounded.  

كَانَ رَسُولُ اللَّهِ ﷺ يَغْزُو بِأُمِّ سُلَيْمٍ وَنِسْوَةٍ مِنَ الأَنْصَارِ مَعَهُ إِذَا غَزَا فَيَسْقِينَ الْمَاءَ وَيُدَاوِينَ الْجَرْحَى  

"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."  

كَانَ رَسُولُ اللَّهِ ﷺ يَغْزُو بِأُمِّ سُلَيْمٍ وَنِسْوَةٍ مَعَهَا مِنَ الأَنْصَارِ يَسْقِينَ الْمَاءَ وَيُدَاوِينَ الْجَرْحَى  

[Machine] The translation of the sentence is: "The Messenger of Allah ﷺ used to take women from the Ansar with us to water the wounded during the battles."  

«كَانَ رَسُولُ اللَّهِ ﷺ يَغْزُو بِنَا مَعَهُ نِسْوَةٌ مِنَ الْأَنْصَارِ لِتَسْقِيَ الْمَاءَ وَتُدَاوِيَ الْجَرْحَى»  

[Machine] "The Messenger of Allah ﷺ used to go on expeditions with us, accompanied by some women from the Ansar. We would fetch water and tend to the wounded."  

«كَانَ رَسُولُ اللَّهِ ﷺ يَغْزُو بِنَا مَعَهُ نِسْوَةٌ مِنَ الْأَنْصَارِ نَسْقِي الْمَاءَ وَنُدَاوِي الْجَرْحَى»  

"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»
