legality of freezing incurable patients from the viewpoint of Islamic Jurisprudence religions

One of the new issues that have emerged in the field of physics is Cryonics. Cryonics is a kind of protecting the legally dead humans or animals in a very low temperature, in the hope that the future medicine will survive them. But the criterion for death is almost always stopping the heart. In contemporary medicine, brain death is considered a definitive criterion of death; although such people are medically alive but are considered dead. The only way to cure a terminal patient who is dying is freezing. In this study, the legitimacy of such action should be investigated with respect to the specific constraints, in terms of religious faith. For this, the first chapter explains the issue of Cryonics. To clarify the issue, international organizations active in the field of Cryonics were used and the intermediaries were avoided as far as possible. In the second chapter, the evidence of licensed and non- licensed Cryonics is discussed. All investigations can be concluded that firstly the licensed evidence has fewer problems than the non-licensed evidence and freezing a terminal patient is prohibited given the desired constraints. Secondly, assuming that the non-licensed evidence, then we have no choice in preferring the important thing that is the preserve of patient’s life (freezing).
