If one might be permitted a somewhat reductionist synoptic contrast between the three Abrahamic religions, Islam could perhaps be placed midway between what might be termed a legalistic Judaism and a theological Christianity. That is because it is a virtually unquestioned assumption in modern Islam that theology and legal reasoning in Islam are permissible only to ascertain God’s will expressed in the Qur'ān and the Sunnah. In other words, generally accepted Islamic scholarship holds that these primary sources constitute the authentic and foundational sources of law and religious and legal practice are organically linked to them. Thus, it is widely accepted that no human jurisprudential innovation that explicitly contradicts the Qur'ān and the Sunnah has ever managed to be incorporated into the body of literature that governs Muslims' practices and worship.
