Zahirism (Majatran: ظاهرية Ẓāhirīyyah) is a heterodox offshoot of Abadi Ahmadism emerging in 37th century Wantuni in response to the rise of the contested Razamid Caliphate. Zahiris are distinguished from Abadis by their belief in the office of the Imam (lit. "Leader"), the spiritual and political successor to Prophet Ahmad. More specifically Zahiris accept Zahir al-Muntadhir, a 37th century Majatran from Wantuni, as the rightful Imam in opposition to the usurper Caliph Khalid I, and they believe that al-Muntadhir is still alive and his return will herald the end of the world.
