Aqidah (sometimes spelled Aqeeda, Aqidah or Aqida) (Arabic: عقيدة plural عقائد 'aqā'id‎) is an Islamic term meaning creed. Any religious belief system, or creed, can be considered an example of aqidah. However this term has taken a significant technical usage in Muslim history and theology, denoting those matters over which Muslims hold conviction. There are three main accepted schools of Sunni Aqidah: Ashari, Maturidi and Athari.
