It has been narrated on the authority of Abd-ul-Aziz bin Abu Hazim, who learnt from his father (Abu Hazim). The latter heard it from Sahl bin Sad who was asked about the injury which the Messenger of Allah ﷺ got on the day of the Battle of Uhud. He said: The face of the Messenger of Allah ﷺ was injured, his front teeth were damaged and his helmet was crushed. Fatima, the daughter of the Messenger of Allah ﷺ , was washing the blood (from his head), and Ali bin Abu Talib was pouring water on it from a shield. When Fatima saw that the bleeding had increased on account of (pouring) water (on the wound), she took a piece of mat and burnt it until it was reduced to ashes. She put the ashes on the wound and the bleeding stopped.
