The Book Pertaining to Punishments Prescribed by Islam (Kitab Al-Hudud)
Muslim :: Book 17 : Hadith 4232
Ali reported: If I impose Hadd on anyone, and he (in course of punish ment) dies, I would not mind except in case of a drunkard. If he dies. I would pay indemnity for him because the Messenger of Allah (may peace be upon him) has laid down no rule for it.
