Ismailis

Ismailism (الإسماعيلية‎‎) is a branch of Shia Islam. The Ismaili get their name from their acceptance of Imam Isma'il ibn Jafar as the appointed spiritual successor (Imam) to Ja'far al-Sadiq, wherein they differ from the Twelvers who accept Musa al-Kadhim, younger brother of Isma'il, as the true Imam.
