One of the most important epistemological foundations of Islamic humanities is the authority and validity of revelation. From the point of view of Islamic epistemology, experience is not the only way to acquire knowledge and knowledge, but reason and revelation are the most important tools of knowledge and sources of knowledge. This issue has a serious role in human sciences and in describing and prescribing human actions. In this research, the ability and capacity of revelation in producing the foundations and ideas of human sciences is explained based on three basic features of revelation from the point of view of theologians, i.e. infallibility, realism, and maximum scope in relation to the affairs of individual and social human life. This issue is based on This important point that the theories of experimental knowledge, including the human sciences, although they refer to objectivity, but do not fully match with objectivity, but merely represent a corner of reality, creates a wide possibility and field for the entry of sources of religious knowledge in the field of theorizing Islamic humanities. This capability is not exclusive to the position of collecting assumptions, but also exists in the judging stage, both description and prescription. According to the results of this research, the entry of revelation into the field of human sciences does not mean denying the experience and testability of theories, but the revelation propositions that are directly or indirectly able to be experimentally tested will play a role in the production of human sciences.
