The Islamic Messiah is known as the Mahdi, which is a five-letter Arabic word meaning 'the guided one'. The Mahdi is believed to be a descendant of the Prophet Muhammad who will appear at the end of time to restore justice and peace to the world. He is also seen as a messianic figure who will bring about the final triumph of Islam. The Mahdi is expected to bring about a period of global peace and justice, and will be accompanied by Jesus, who will help him in his mission.
