Sahih al-Bukhari 4075
Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)
The wounds inflicted on the Prophet (ﷺ) on the day (of the battle) of Uhud
Narrated Abu Hazim: That he heard Sahl bin Sa`d being asked about the wounds of Allah's Messenger (ﷺ) saying, "By Allah, I know who washed the wounds of Allah's Messenger (ﷺ) and who poured water (for washing them), and with what he was treated." Sahl added, "Fatima, the daughter of Allah's Messenger (ﷺ) used to wash the wounds, and `Ali bin Abi Talib used to pour water from a shield. When Fatima saw that the water aggravated the bleeding, she took a piece of a mat, burnt it, and inserted its ashes into the wound so that the blood was congealed (and bleeding stopped). His canine tooth got broken on that day, and face was wounded, and his helmet was broken on his head."
