`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."

← Previous Hadith On the day (of the battle) of Uhad when (some) people retreated and left the Prophet, I saw `Aisha bint Abu Bakr and Um Sulaim, with their robes tucked up so that the bangles around their ankles were visible hurrying with their water skins (in another narration it is said, "carrying the water skins on their backs"). Then they would pour the water in the mouths of the people, and return to fill the water skins again and came back again to pour water in the mouths of the people.
