Ungefär som kristendomens Messias.
For Jews the Messiah is the long-awaited man anointed of God to provide the chosen people and the world at large with a just, durable and peaceful social order in accordance with the Torah and God's ultimate purpose for mankind. For Christians Jesus was the Messiah (Greek: Christ) who came to fulfill that hope, teach men the religion of love, serve as an example of what God expects of His children, cleanse them of original sin, joint them toward the kingdom to come wherein God's will would be done on earth as it is in heaven. Since the first advent did fully accomplish this, traditional Christianity looks forward to the return of the Messiah to complete the restoration of the world. Like many Christians, not all Muslims expect an end of the world g the immediate future. However, Sunnite doctrine teaches that at some future time, a Mahdi will come to establish the kingdom of God on earth. Shi'ites believe that this Mahdi to come will be the hidden Imam they have long awaited. For Muslims the Imam-Mahdi is a figure with a function comparable to that of the Christian Messiah. Thus, like Judaism and Christianity, Islam can be called a messianic faith.
