Sunna (Arabic, custom, or rule), a collection of oral traditions of the sayings and practices of Mohammed and his wives, companions, and immediate successors. The believers in them are called Sunnis. They are considered the orthodox Mohammedans, and comprise the four sects of Hanifites, Malekites, Shafeites, and Hanbalites, named after their founders, all of whom recognize the Sunna as of a value second only to that of the Koran, which the Shiahsdeny. (See Shiahs.) The Sunna is also known under the name Hadis, "Tradition." While the Shiahs constitute at present the majority of the Persian and Hindoo Mohammedans, the Sunnis, and among them especially the Malekites and Shafeites, are dominant in the Ottoman empire, Arabia, Turkis-tan, and Africa.
