The dual nature of human existence and having both physical and spiritual aspects are accepted by religious scholars and divine philosophers. Despite the disagreement on the way that soul was created, Muslim philosophers have agreed about “the creation of soul and not being presiding over body.” While Avicenna has proved this idea through two arguments in his book al- Shifa, Mulla Sadra has brought different arguments in favor of this idea. He accepted some of them and rejected others. On the other hand, many textual proofs imply that soul was created before body. This article study and analyze the idea of “synchrony of creation of soul and body” on which most Muslim philosophers agree. With regard to evaluation of philosophers' arguments who believe the thought and for criticism of their argument, the author shows that the conflict between intellect and implication of quotation is just a claimed conflict.
