This graphic description of this particularly brutal and horrible method of execution quotes the Iranian Penal Code. Iran has reportedly amended its internationally condemned law on stoning convicted adulterers to death to allow judges to impose a different form of execution in 2013:
At least 150 people may have been stoned in Iran since 1980, the International Committees against Execution and Stoning said in 2010.
According to local media, MPs had removed stoning altogether from the bill that they adopted. But the hardline Guardians Council of clerics and jurists, which must approve all legislation before it enters into force, reinserted it, with the new amendment.
However this document graphically illustrates the brutal and inhumane process for stoning under sharia law and several Islamic countries still have stoning as a method of execution for certain crimes, particularly adultery.
