In Islamic eschatology, the Mahdi (Arabic: مهدي / ISO 233: mahdī / English: Guided One) is the prophesied redeemer of Islam who will rule for seven, nine or nineteen years (according to various interpretations) before the Day of Judgment (yawm al-qiyamah / literally, the Day of Resurrection) and will rid the world of evil. Isa (Jesus Christ) will return to aid Mahdi, or the guided one, against Masih ad-Dajjal, the false messiah, and his followers.He will descend at the point of a white arcade, east of Damascus, dressed in yellow robes with his head anointed. He will then join the Mahdi in his war against the Dajjal. Isa will slay Dajjal, and unite humanity. Sahih Muslim, 41:7023 Sahih al-Bukhari, 3:43:656: Narrated Abu Hurairah: Allah's Apostle said, "The Hour will not be established until the son of Maryam descends amongst you as a just ruler; he will break the cross, kill the swine, and abolish the Jizya tax. Wealth will be in abundance so that nobody will accept it." Jesus Christ has been foretold to return at near the end of the world. The Qur'an says: “And [Isa] shall be a Sign (for the coming of) the Hour (of Judgment): therefore have no doubt about the (Hour), but follow ye Me: this is a Straight Way.
