The people differed about the type of treatment which had been given to Allah's Messenger (ﷺ) on the day (of the battle) of Uhud. So they asked Sahl bin Sa`d As-Sa`id who was the only surviving Companion (of the Prophet) at Medina. He replied, "Nobody Is left at Medina who knows it better than I. Fatima was washing the blood off his face and `Ali was bringing water in his shield, and then a mat of datepalm leaves was burnt and (the ash) was inserted into the wound."
