Mahdi claimants

In Muslim eschatology, the Mahdi is a Messianic figure who, it is believed, will appear on Earth before the Day of Judgment, and will rid the world of wrongdoing, injustice and tyranny. People claiming to be the Mahdi have appeared across the Muslim world – in South Asia, Africa and the Middle East – and throughout history since the birth of Islam (AD 610).

A claimant Mahdi can wield great temporal, as well as spiritual, power: claimant Mahdis have founded states (e.g. the late 19th-century Mahdiyah in Sudan), as well as religions and sects (e.g. Bábism, or the Ahmadiyya movement). The continued relevance of the Mahdi doctrine in the Muslim world was most recently emphasised during the 1979 seizing of the Grand Mosque in Mecca, Saudi Arabia, by at least 200 militants led by Juhayman al-Otaibi, who had declared his brother-in-law, Muhammad bin abd Allah al-Qahtani, the Mahdi.

Ṣāliḥ ibn Tarīf, the second king of the Berghouata, proclaimed himself prophet of a new religion in the 8th century. He appeared during the caliphate of the Umayyad Hisham ibn Abd al-Malik. According to Ibn Khaldun's sources, he claimed receiving a new revelation from God called a Qur'an, written in the Berber language with 80 chapters. He established laws for his people, which called him Salih al-Mu'minin ('Restorer of the Believers'), and the final Mahdi.
