Epistemology of Sunni Kalam through the prism of “Kitab alTawhid” by al-Maturidi

The object of the study is the work of a well-known Hanafi authority Abu Mansur alMaturidi “Kitab al-Tawhid”, where he examines the ways of learning. The analysis displayed the fact that the theologian, adhered to the idea of the admissibility of the world cognition, identifi ed three ways of cognizing: by sense organs (‘iyan), by tradition or legend (khabar) and by mind (‘aql), which, in his opinion, are sources of any knowledge, in general, and of the theological one, in particular. The theologian believed that all the three generate the so-called categorical knowledge, which makes it possible to substantiate the main propositions of the Islamic creed.
