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  

When the Messenger of Allah ﷺ went on an expedition, he took Umm Sulaym, and he had some women of the Ansar who supplied water and tended the wounded.  

كَانَ رَسُولُ اللَّهِ ﷺ يَغْزُو بِأُمِّ سُلَيْمٍ وَنِسْوَةٍ مِنَ الأَنْصَارِ لِيَسْقِينَ 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 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»  

[Machine] The Messenger of Allah ﷺ used to take us on expeditions with him, to serve the women among the Ansar. We would provide water to the sick and nurse the wounded.  

كَانَ رَسُولُ اللهِ ﷺ «يَغْزُو بِنَا مَعَهُ لِنِسْوَةٍ مِنَ الْأَنْصَارِ فَنَسْقِي الْمَرْضَى وَنُدَاوِي الْجَرْحَى»
