Criticism of Twelver Shia Islam
Criticism of Twelver Shia Islam dates from the initial ideological rift among early Muslims that led to the two primary denominations of Islam, the Sunnis and the Shias. The question of succession to Muhammad, the nature of the Imamate, the status of the twelfth Shia Imam, and other areas in which Twelver Shia Islam differs from Sunni Islam have been subjects of criticism by Sunni scholars, even though there is broad agreement between the two traditions regarding the centrality of the Quran, Muhammad, and many doctrinal, theological, and ritual matters.
