Traditional theory of Islamic jurisprudence recognizes four sources of Sharia: the Quran, "sunnah" (authentic hadith), "qiyas" (analogical reasoning), and "ijma" (juridical consensus). Different legal schools—of which the most prominent are Hanafi, Maliki, Shafiʽi school, Hanbali and Jafari—developed methodologies for deriving Sharia rulings from scriptural sources using a process known as "ijtihad". Traditional jurisprudence ("fiqh") distinguishes two principal branches of law, "ʿibādāt" (rituals) and "muʿāmalāt" (social relations), which together comprise a wide range of topics. Its rulings are concerned with ethical standards as much as with legal norms, assigning actions to one of five categories: mandatory, recommended, neutral, abhorred, and prohibited. Thus, some areas of Sharia overlap with the Western notion of law while others correspond more broadly to living life in accordance with God's will.
