Prophecy is a process in which one or more messages that have been communicated to a prophet are then communicated to others. Such messages typically involve divine inspiration, interpretation, or revelation of conditioned events to come (cf. divine knowledge) as well as testimonies or repeated revelations that the world is divine. The process of prophecy especially involves reciprocal communication of the prophet with the (divine) source of the messages. Throughout history, clairvoyance has commonly been used and associated with prophecy.

Various concepts of prophecy are found throughout all of the world's religions and cults. To a certain degree prophecy can be an integral concept within any religion or cult. The term has found deep usage in the Abrahamic religions, including Judaism, Christianity, Islam, and Baha'i along with many others.
