The celestial reincarnation of soul is the most important image that Mulla Sadra presents for the physical resurrection, in the sense that the human soul after being separated from the physical body, will be summoned into a body made by him in physical world based on his inner attributes and properties. The Holy Qur'an describes a group of Israelites who appeared in the form of monkeys as a result of their disobedience to God’s commandments. Mulla Sadra considers the Israelites’ disfigurement and the general phenomenon of disfigurement as a proof of celestial reincarnation. Considering Mulla Sadra's multiple principles and the preliminaries he provided to prove celestial reincarnation, it is possible to achieve this confirmation. This article attempts to explain this confirmation through studying the reality of celestial reincarnation and disfigurement phenomenon.
