The Shiites believe that divine Imams are heirs to the political and religious Ummah, or Islamic nation. These 12 imams are successors to the Prophet Muhammad and to the head of the caliphate, with Mahdi being the final Imam who disappeared, or went into occultation. Mahdi will be revealed only in the end-times, along with Jesus, to deliver peace to the world.
According to the book “250 Signs Until the Appearance of Imam Mahdi,” Prophet Muhammad said: “On doomsday, a man who is carrying the name of an animal ascends to the throne, after which a man named Abdullah comes to the power. Whoever informs me of his death, I will inform him of the rise [of Mahdi]. After Abdullah passes away, for several days and months, the government will appear.”
A seminary teacher based in Qom told Al-Monitor on condition of anonymity, “The animal-named man can be King Fahd because one meaning of Fahd’s [name] is rapacious animal and cheetah, which matches what Prophet Muhammad said.”
