Ma`rifat Kalami

There is no doubt that the epistemological foundations of an intellectual system play a significant role in its definition of human identity. The movement of Salafism presents a completely material definition of the world of being and human in the light of the foundations of extreme empiricism. One of the pioneers of Salafism, Ibn Qayyim Joziyeh, defines the human soul as a "subtle substance" that flows through all parts of the body. In terms of methodology, Ibn Qayyim relies on Islamic narrations and the understanding of righteous predecessors (Salaf Saleh). He has criticized the arguments presented by philosophers about the immateriality of the soul and has provided some arguments for the materialization of the soul. I have first explained the epistemological and ontological bases of Ibn Qayyim in this article, and then I have analyzed and criticized his definition of human’s “soul and spirit”, and also evaluated his reasons for denying the immateriality of the soul and proving its materiality.
