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 (may peace be upon him). (With this introduction) he narrated a number of traditions. One of these was that the Messenger of Allah (may peace be upon him) said: Great is the wrath of Allah upon a people who have done this to the Messenger of Allah (may peace be upon him), and he was at that time pointing to his front teeth. The Messenger of Allah (may peace be upon him) also said: Great is the wrath of Allah upon a person who has been killed by the Messenger of Allah (may peace be upon him) in the way of Allah, the Exalted and Glorious.
