Since pre-Islamic times, the Arabic word sunnah has referred to a body of established customs and beliefs that make up a tradition. In Muslim legal and religious thought, the term became associated more specifically with the actions and sayings of the Prophet Muhammad. Inspired by God to act wisely and in accordance with his will, Muhammad provided an example that complements God’s revelation as expressed in the Qur’an. His actions and sayings became a model for Muslim conduct as well as a primary source of Islamic law.
