Criminals culpable of inflicting an injury on another person get that same injury exactly to the centimetre. I mean they measure the victim's injury with a ruler then transfer the markings to the same body part on the criminal before inflicting the same injury as punishment.
The pictures below show two men being harmed had allegedly slashed the head of a man in the Iraqi city of Mosul.
The images were posted online by anti-ISIS activists who are fierce opponents of the militants' brutal practices.
The new list of religious punishments which include: public crucifixion, stoning to death and gay men being thrown from buildings are said (by ISIS) to be based on Sharia law. Recently the group shot a group of doctors to death for not treating injured members.
