In the present research, various definitions of the term "essence" and its function in the question of "authenticity or validity of essence" are discussed. The author's specific method is based on the conceptual analysis of opinion polls in terms of the historical course of philosophical schools. The first-hand work shows that al-Farabi, by expressing certain terms, believed that external existences existed. Later, the terminology and kind of his view were deployed in the philosophy of Sinai. Suhrawardi, in terms of the meaning of "We gave al-Shao Ho Ho" for essence, its originality and the validity of "existence." In contrast, Mulla Sadra established the meaning of the "essence" in his philosophy and voted for the validity of the nature; but some people are precise to find that, in Sadra's philosophy, there is confusion between the essence of the mind and the external nature, and in the word "essence" It has been forged. Sheikh Ahsaee and Mirza Isfahani also, with the introduction of new terms, considered the combination of concrete and a combination of existence and nature. The result of the statement is that the promise of the originality or validity of the essence of the concept of any thinker originates from this term, not the pseudo-reasons. Therefore most Muslim thinkers, according to the realist approach, at least adhere to the principle of the essence of the belief.
