Pronounced “ee-MAHM.” In everyday use, any person who leads a congregational prayer. Traditionally, only men have been imams, although women are allowed to serve as imams for other women. To lead prayers, one does not have to be a cleric. In a more formal sense, an imam is a religious leader, but can also be a political leader. Many Shiites believe imams are intercessors with God; many also believe in the Twelve Imams, descendants of Prophet Muhammad whom they consider his rightful successors. The Twelfth Imam disappeared from the world in 873, but followers of Twelve Imams Shiism believe that he is still alive and will return as the Mahdi, or “the guided one,” who will restore righteousness before the end of the world. On first reference, uppercase imam when preceding a proper name. On second reference, use only the person’s last name. Uppercase imam when referencing the Twelve Imams.
