It has been narrated on the authority of Abd-ul-'Aziz b. Abu Hazim, who learnt from his father (Abu Hazim). The latter heard it from Sahl b. Sa'd who was asked about the injury which the Messenger of Allah ( صلی اللہ علیہ وسلم ) got on the day of the Battle of Uhud. He said:
The face of the Messenger of Allah ( صلی اللہ علیہ وسلم ) was injured, his front teeth were damaged and his helmet was crushed. Fatima, the daughter of the Messenger of Allah ( صلی اللہ علیہ وسلم ), was washing the blood (from his head), and 'Ali b. 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.
