On the authority of Jundub ibnAbdullah (may Allah be pleased with him), who said that the Messengerof Allah  said:

There was amongst those before youa man who had a wound. He was in [such] anguish that he took a knifeand made with it a cut in his hand, and the blood did not cease to flowtill he died. Allah the Almighty said: My servant has himselfforestalled Me; I have forbidden him Paradise.
