Bismillah Walhamdulillah Was Salaatu Was Salaam ‘ala Rasulillah Narrated Jundub (Radi-Allahu ‘anhu):

Allah’s Apostle (Sallallahu ‘Alaihi Wa Sallam) said, “Amongst the nations before you there was a man who got a wound, and growing impatient (with its pain), he took a knife and cut his hand with it and the blood did not stop till he died. Allah said, ‘My Slave hurried to bring death upon himself so I have forbidden him (to enter) Paradise.’ ”
