Imam Mahdi — Islamic Beliefs About the Awaited Savior
What Sunni, Shia and Salafi sources actually say about the Mahdi, the occultation, and awaiting with action.
Belief that God will send a guided leader to fill the earth with justice after it has been filled with oppression is not a sectarian peculiarity. It is reported in Sunni, Shia and Salafi hadith literature alike; the schools differ over identity and mechanism, not over the promise.
The Sunni position
Sunan Abi Dawud, Sunan al-Tirmidhi and Sunan Ibn Majah contain a "Book of the Mahdi". The reports state that he will be of the Prophet's family, from the descendants of Fatimah, that his name will match the Prophet's, that he will rule seven or nine years, and that Isa (Jesus) will descend and pray behind him. Ibn Khaldun questioned some chains, but the doctrine is affirmed by the great majority of Sunni scholars, and the Salafi tradition affirms it explicitly — Ibn Baz and Ibn Uthaymin both stated the reports reach the level of mutawatir in meaning.
The Shia position
Twelver Shia belief identifies the Mahdi as Muhammad ibn al-Hasan al-Askari, born in Samarra in 255 AH, the twelfth Imam. He entered a minor occultation (874–941 CE) during which four successive deputies relayed communication, and then the major occultation, which continues. In his absence, general authority passes to qualified jurists (niyabah ammah), the basis of the modern institution of marja'iyyah.
Signs and cautions
Sources mention the appearance of Sufyani, a cry from the sky, the emergence of Dajjal, and the descent of Isa. Every school also warns against date-setting and against claimants: history is full of failed Mahdis, and the Prophet warned of many liars.
Awaiting correctly
The strongest teaching in both traditions is that intizar — awaiting — is active, not passive. The Imams taught that the best deed is "awaiting relief" while preparing oneself: acquiring knowledge, establishing justice locally, and living so that one would be fit to serve him if he appeared tomorrow. A person waiting for a just leader while ignoring injustice within reach has misunderstood the belief.
