Islam
Ibadiyya (Oman)
The Ibadiyya Muslim community can be traced to a seventh century schism in the Muslim community over the leadership of Ali ibn Abi Talib to serve as the Caliph. They came to opposed any leadership succession based on geneology in favor of the selction of the best leader from among those available. It is the dominant form of Islam in Oman, and has a following in various parts of Africa and elsewhere.
