 Some Sunni beliefs deny the Mahdi as a separate figure, accordingly Jesus will fulfill this role and judge over mankind, thus "Mahdi" is considered as a title for Jesus, when he returns.However the more common opinion among Sunni Muslims is, that the Mahdi is an expected ruler sent by God before the endtime to reestablish righteousness, coincides with the Second Coming of Jesus Christ ("Isa"), but, unlike most Shia traditions, Sunni Islam often do not believe the Mahdi has already been born.Sunnis in general reject the Twelver Shi'ite principle of the Mahdi's occultation.
