Raj`a (الرجعة, romanized: āl rj'ah, lit. 'Return') (alternatively rjaa, raja'a, raj'at) in Islamic terminology, refers to the Second Coming, or the return to life of a given past historical figure after that person's physical death. While primarily used in Shia Muslim terminology, variations on the doctrine exist in Sunni Islam and the Bahá'í Faith, and raj`a is used to describe certain Christian doctrines in Arabic.
