Ibadism is one of the main sects of Islam along with Sunni and Shi'i Islam. Ibadi Islam emerged around 20-60 years after Prophet Muhammad's death in 632 AD.
Ibadism, a distinct sect of Islam that is neither Sunni nor Shi‘i, exists mainly in Oman, East Africa, the Mzab valley of Algeria, the Nafus mountains of Libya, and the island of Jerba in Tunisia. The sect developed out of the seventh-century Islamic sect known as the Khawarij, and shares with that group the desire to found a righteous Muslim society and the belief that true Muslims are only to be found in their own sect. Ibadis refer to themselves as “the Muslims” or “the people of straightness” (ahl al-istiqama). Nonetheless, Ibadis see themselves as quite different from Khawarij. - Valerie Hoffman, An Introduction
