In Twelver Shia Islam, the Major Occultation (Arabic: ٱلْغَيْبَة ٱلْكُبْرَىٰ, al-Ghaybah al-Kubrā, 329 AH-present, 941 CE-present) is the second occultation of the Hidden Imam, Muhammad al-Mahdi, which is expected to continue until his rise in the end of time to establish peace and justice on earth. While various sects disagree about the identity of the eschatological Mahdi, the belief in him remains popular among all Muslims, possibly owing to numerous traditions to this effect in canonical Sunni and Shia sources.
