While the Quran does not state that he will come back, Islamic tradition nevertheless believes that Jesus will return at the end of times, shortly preceding "Mahdi", and exercise his power of healing. He will forever destroy the falsehood embodied in "al-Masih ad-Dajjal" (the false Messiah), the great falsifier, a figure similar to the Antichrist in Christianity, who will emerge shortly before "Yawm al-Qiyāmah" ('the Day of Resurrection'). After he has destroyed ad-Dajjal, his final task will be to become leader of the Muslims. Isa will unify the Muslim "Ummah" (the followers of Islam) under the common purpose of worshipping Allah alone in pure Islam, thereby ending divisions and deviations by adherents. Mainstream Muslims believe that at that time, Isa will dispel Christian and Jewish claims about him.
