The death penalty is a legal process whereby a person is put to death by the authority as a punishment for a crime. Execution has been a common punishment throughout the history since middle ages. Various methods of execution are used worldwide in the civilized nations. About one third of the countries in the world have laws that allow the death penalty. For an increasing number of countries, the death penalty is a critical human rights issue. Penalties involving torture disappeared with the idea that punishment and death should be swift and humane. Currently used methods are: firing squad, hanging, stoning, lethal injection, electrocution, gas chamber and beheading. Each method was discussed according to the applied procedure, time and cause of death, painful experience by the victim and any subsequent mutilating effects. As death rows around the nation swell with inmates, prison officials are grappling with a question: How to execute a condemned criminal professionally and humanely? Although, death penalty is justified by religions, yet there’s no special recommendation for a special method of application except frank order for stoning in the Old Testament and special recommendation in Hadith for stoning but in certain crimes under very strict conditions.
