The Iranian law, given its deep roots in the Shiite jurisprudence, has incorporated the punishment of haddi theft in article 278 of the Islamic Penal Code of 2013. The punishment is, for the first time, amputation of the thief’ s right fingers. The question of this paper is whether amputation of thief’ s right fingers is an absolute ruling and must be administered in all circumstances or in specific cases, this principle is restricted and the amputation of the right hand is not administered. A hypothesis has been discussed in Islamic jurisprudential books: where the thief lacks the left hand is it permitted to administer the hadd of amputation of the right hand to him? The famous Islamic jurists, relying on the Holy Quran and Sunna have accepted the viewpoint that in such case the right hand is amputated; on the contrary, a group of Islamic jurists have preferred non-amputation. In the present paper, through an analytical-descriptive method and taking into account the Usul-al-Fiqh principles, and after evaluating the evidences of the two groups, the authors have concluded that in case the thief does not have the left hand, his right hand mustn’ t be amputated and the hadd of theft is not applicable to him. Given the fact that the Islamic penal law of 2013 has not dealt with this issue and the legislator has not adopted a positive or negative attitude, it has been recommended in this paper to amend the law and prescribe this issue therein.
