The Mahdi is mentioned in the Qur'an: "Follow those who do not ask you for any wage and who have received guidance. (MUHTADUN –plural for Mahdi in Arabic)" (Surah Ya Sin 21) All the prophets, including the Prophets Abraham, Jacob and Moses, have anticipated the Mahdi. They all have awaited the Mahdi in fervor and eagerness. - Harun Yahya
