Jundub b. ‘Abdallah reported Allah's Messenger ﷺ as saying that among those who lived before their time there was a man who had a wound and had so little patience to bear it that he took a knife with which he cut off his hand, but the blood did not cease to flow till he died. Allah most high said, “My servant has tried to outstrip me in taking his life, so I have excluded him from paradise.” (Bukhari and Muslim.)
