We were in the company of the Prophet (ﷺ) providing the wounded with water and treating them and bringing the killed to Medina (from the battle field) .
Sahih al-Bukhari Book 56, Hadith 97
← Previous Hadith `Umar bin Al-Khattab distributed some garments amongst the women of Medina. One good garment remained, and one of those present with him said, "O chief of the believers! Give this garment to your wife, the (grand) daughter of Allah's Messenger (ﷺ)." They meant Um Kulthum, the daughter of `Ali. `Umar said, Um Salit has more right (to have it)." Um Salit was amongst those Ansari women who had given the pledge of allegiance to Allah's Messenger (ﷺ).' `Umar said, "She (i.e. Um Salit) used to carry the water skins for us on the day of Uhud."
