Mukhtasar Bukhari

Narrated Sayyiduna Jundub bin Abdullah (may Allah be pleased with him): The Messenger of Allah (peace and blessings of Allah be upon him) said: "There was a man among the people before you who was wounded. He took a knife and cut his hand, and the blood kept flowing (and did not stop) until he died. So Allah the Exalted said: 'My servant hastened his soul; I have made Paradise forbidden for him.'"
