From Sahih Muslim (Hadith 4648):
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 (ﷺ). (With this introduction) he narrated a number of traditions. One of these was that the Messenger of Allah (ﷺ) said: Great is the wrath of Allah upon a people who have done this to the Messenger of Allah (ﷺ), and he was at that time pointing to his front teeth. The Messenger of Allah (ﷺ) also said: Great is the wrath of Allah upon a person who has been killed by the Messenger of Allah (ﷺ) in the way of Allah, the Exalted and Glorious
