In the study of religions the term "divine revelation" is usually used to indicate the supernatural origin of a set of beliefs or sacred texts. It is in this sense that the classic religions which originated in the Middle East have been regarded as "revealed religions". The founders of these religions are regarded by their followers either as "prophets" chosen by God to act as a mouthpiece for his communication with humans (as is the case of Mohammad in Islam), or as God himself in some disguise (as with Jesus in Christianity). The "truth" of these religions is attributed to their supposed divine origin, and indeed the followers of these religions do not apply to the claims of their founders the normal criteria that are used to establish the truthfulness of other claim.
