Multiplicity of the Islamic Penal Code and its Effects (with Emphasis on Crimes Against Persons)

The application of jurisprudential teachings to customary law in order to formulate laws appropriate to today's society has always been the main concern of Iranian legislators and the penal code is the main focus of this concern where the inflexibility of boundaries with duality of right or retribution is considered alongside the central part of diyat. Narrows down the formulation of laws in accordance with the teachings of customary law. This article uses a descriptive-analytical method and using library sources to answer the question whether the legislator in combining customary law and jurisprudence has been able to impose the requirements of customary law on jurisprudential crimes? The initial answer to this is no, because the nature of the law resulting from the combination of these two views will be accompanied by challenges and ambiguities that can be realized by carefully considering the Islamic Penal Code; Granting the right to punish unqualified persons, such as Article 302 of the Penal Code, the disenfranchisement of perpetrators of serious crimes, including aiding and abetting murder in some cases, such as aiding and abetting a minor crime, is an example of conflict between customary law and jurisprudential teachings.
