Investigation of Repeated Punishment of Deprivation of Life in Imamieh Jurisprudence

In the penal system of Islam, the punishment for some crimes is the deprivation of life of the offender. These punishments have a considerable scope in terms of "Hadd", "Tazir" and "Qisas". Some other crimes include punishments that typically and in accordance with their nature and common law cause the offender to be deprived of life. "Stoning" in adultery and "Hanging" in Moharebeh are examples of the mentioned punishments. But if in the two mentioned cases, the usual and common punishment, does not lead to death of the offender, is the punishment repeated? Or that re-execution of the punishment for deprivation of life requires an independent reason?  The author believes that in crimes, for which the punishment is death or deprivation of life, if the punishment does not lead to death of the offender, the legitimacy of re-enforcing the punishment is not eliminated. But penalties normally cause death, if in a case, accidentally, the common result is not obtained, re-execution of the punishment is not legally acceptable. This theory is in conformity with the original rules of punishments and Interdiction rule.
