The present article explains and analyzes the impact of Suhrawardi's eschatology on Mulla Sadra's philosophy and Sadra's critical evaluation of it. In this research, we have tried to explain and analyze Mulla Sadra's critiques of Suhrawardi's thought about identity, celibacy, self-occurrence, self-survival, and post-mortem souls, and in general, relatively clear pictorial resurrection from Suhrawardi's position in the philosophical system. Let's present Sadra. In this research, we first try to explain and analyze Suhrawardi's eschatology theory in the form of concepts such as the abstraction of occurrence, survival of soul, and finally the state of soul after departure from the body, and then the effect of Suhrawardi's resurrection on Mulla Sadra's thought. We explain and at the end of Mulla Sadra's critiques of Suhrawardi we evaluate and show that most of Mulla Sadra's critiques on the most important issues of Suhrawardi's eschatology do not seem logical. Here, too, we have tried to provide the reader with a fairly accurate analysis of this subject by remaining faithful to the texts of both philosophers and using the opinions of the commentators and experts of these two thinkers.
