In this article, the nature and fundamentals of the theory of "three-layer interpretation of the "Holy Quran" have been studied.First, the theory is defined and comprised three layers: historical, transhistorical and modern.The historical layer has been considered as the understanding of the verses of the Qur'an by Arabs of Hejaz during the holy Prophet (PBUH). To identify such an understanding, one must refer to the promises of those people, the most important of which are the appearance and context of the verses, similar verses, the personality of the Qur'an, the events of that era, the culture and history of those people and the covenants. The transhistorical layer is considered to be an epistemology that is accepted among all human races, achieved by abolishing the temporal-spatial features of the revelation of the Qur'an.The modern layer is the adaptation of the issues, needs and requirements of the present to the same common human knowledge.Some of the most important principles of this theory, which are discussed in this article, : being customary, spoken, gradual, historical ,marginalized on one hand, and the evolution of ethnic requirements, the necessity to resolve the apparent conflict between the Qur'an and science and modernity on the other hand.
