It has been narrated by Hammam b. Munabbih who said:
This is what has been related to us by Abu Huraira from the Messenger of Allah ( صلی اللہ علیہ وسلم ). (With this introduction) he narrated a number of traditions. One of these was that the Messenger of Allah ( صلی اللہ علیہ وسلم ) said: Great is the wrath of Allah upon a people who have done this to the Messenger of Allah ( صلی اللہ علیہ وسلم ), and he was at that time pointing to his front teeth. The Messenger of Allah ( صلی اللہ علیہ وسلم ) also said: Great is the wrath of Allah upon a person who has been killed by the Messenger of Allah ( صلی اللہ علیہ وسلم ) in the way of Allah, the Exalted and Glorious.
