Sonna or Sunna

The Mishna or oral law of the Mahometans. Reland (De Relig. Mahom., p. 54) says these traditions were orally delivered by Mahomet, and subsequently committed to writing. Albulpharaʹgius asserts that Ali, the son-in-law and cousin of Mahomet, was set aside because he refused to regard the oral traditions of the prophet of the same authority as the Koran. (Hist. Dynast., 182.) (Arabic, summa, tradition.) (See Sunnites.)
