The Split in Shia Islam After Imam Ismail’s Death
Imam Ismail’s death before his father created one of the most significant theological divisions in Islamic history, giving birth to the Ismaili branch of Shia Islam.
Twelver Shia Position
Twelver Shia Muslims accepted Imam Musa al-Kazim (AS), the younger brother of Imam Ismail, as the seventh Imam after Imam Jafar al-Sadiq (AS). They reasoned that the Imamate follows the living designated successor, and since Ismail predeceased his father, the designation passed to the next son.
Ismaili Shia Position (The Seveners)
The Ismaili branch, also called “Seveners,” believed that the Imamate was irrevocably vested in Imam Ismail and could not transfer to another. Some believed Imam Ismail had not truly died but had gone into occultation. Others accepted his death but held that the Imamate passed to his son Muhammad ibn Ismail, making him the eighth Imam.
Why Are Ismailis Called Seveners?
Ismailis are called “Seveners” because they recognize only seven Imams ending with either Imam Ismail or his son Muhammad ibn Ismail rather than the twelve recognized by Twelver Shia.
