It has been reported on the authority of Abu Hazim who heard from Sahl bin Sa'd. The latter was asked about the injury of the Messenger of Allah ( صلی اللہ علیہ وسلم ) . He said: By God, I know the person who washed the wound of the Messenger of Allah ( صلی اللہ علیہ وسلم ) , who poured water on it and with what the wound was treated. Then Sahl narrated the same tradition as has been narrated by 'Abdul 'Aziz except that he added the words: "And his face was injured" and replaced the word "Hushimat" by "Kusirat" (i. e. it was broken).
