One of the fundamental principles of Islam is the problem of resurrection. Islamic philosophers consider the principle of resurrection essential, but they are divided as regards its being spiritual or corporeal. Philosophical efforts of Avicenna and Sheikh Eshraq did not lead to the rational acceptance of corporeal resurrection. Sadr al-Mutalhin of Shiraz is the only one whose philosophical effort has led to the rational demonstration of corporeal resurrection. Sadra regards corporeal resurrection a noble pillar of faith and considers its despiser infidel both from rational and traditional points of view. The achievements of Sadra owe their existence to some basic principles of resurrection – which can be divided into two fundamental ontological and anthropological classes. By a descriptive-analytic method, in the current essay we seek to explain the ontological foundations and principles of Sadra concerning corporeal resurrection like primacy of existence, determinateness of existence, analogical gradation of existence, substantial movement and personal unity of existence and show their relevance and the role each one of them has in corporeal resurrection.
