Crime is defined as “the legal prohibition which God punished with hadd and ta’zir. ” These prohibitions have been determined by the primaTy sources of Islamic Law with some terms describing evil or with a punisment fixed in return of bad doings. Every crime ignores a protected value. An act can be regarded as a crime on condition that its legal, material and moral elements completely come into being. Islam basically aims at the disappearance of acts considered crime. For this reason, it educates the people in terms of belief and moral and takes preventive measures. In spite of all measures taken before the commitment of crime, if the crime is commited, a preventive and improving punishment, in accordance with the nature of crime, is fixed. These punishments are equal to the crimes, and should not aim at revenge and unjustice
