Mishkat al-Masabih 19 Jihad كتاب الجهاد 152

وَعَنْ أَنَسٍ قَالَ: كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَغْزُو بِأُمِّ سُلَيْمٍ وَنِسْوَةٍ مِنَ الْأَنْصَارِ مَعَهُ إِذَا غَزَا يَسْقِينَ الْمَاءَ وَيُدَاوِينَ الْجَرْحَى. رَوَاهُ مُسلم

Anas told that when God’s Messenger went on an expedition he took Umm Sulaim, and he had some women of the Ansar who supplied water and tended the wounded when he made an expedition. Muslim transmitted it.
