Dajjal

Al-Masih ad-Dajjal (Arabic: المسيح الدجّال‎ Al-Masīḥ ad-Dajjāl, "the false messiah, liar, the deceiver") is an evil figure in Islamic eschatology. He is to appear, pretending to be al-Masih (i.e. the Messiah), before Youm al-Qiyamah (the Day of Resurrection). He is an anti-messianic figure, comparable to the Antichrist in Christian eschatology and to Armilus in medieval Jewish eschatology.
