The nature of death and the quality of the afterlife depends on the nature of the human person. Among the prominent Imami scholars of kalam, al-Shaykh al-Mufīd holds that the human being is a soul that has a body, and Life is not essential to the body, while for al-Sayyid al-Murtaḍā, the human being is the visible body with its particular structure which can have life in appropriate conditions. The disagreement is reflected in their definitions of the nature of death and the quality of the afterlife. For al-Sayyid al-Murtaḍā, death is a gradual destruction of the human being starting with the collapse of the body and ending with the destruction of its component parts on the verge of resurrection. However, for al-Shaykh al-Mufīd, death is a destruction of the mundane body and the transfer of the soul to the Heaven or the Hell- although, in his view, it is not the case that mundane bodies of all human beings are destroyed, neither is it the case that souls of all human beings are transferred-, and then the destruction of everything, even the souls that live in Barzakh (i.e. intermediate life or purgatory), just before the resurrection. They, nevertheless, believe that the resurrection is a re-creation of what was destroyed. This paper seeks to analyze and examine the views of them regarding the nature of death and the quality of the afterlife.
