A critical review of the evidence of brain death determinism

Brain death means permanent and irreversible stopping of all brain functions in such a way that there is no hope of returning to the previous state. In medical science, brain death is absolute death, but in religious jurisprudence it is controversial. Many attempts have been made to explore its sharia ruling, but each researcher has paid attention to one specific part of its evidence. The evolution of the debate and the discovery of new evidences by researchers have been the reasons for such variation in ideas. Now that all the possible evidences have been presented, in the current study, based on the library research method and comprehensive tracking of the evidences, the question: “How is the probative evidences of those who support the certainty of brain death evaluated?” was answered. It was determined that the probative evidence is incomplete in determining brain death, and a so-called brain-dead person cannot be considered dead, but rather the rulings of a living person should be applied to him/her.
