Fiqh deals with the observance of rituals, morals, and social legislation in Islam as well as the political system. In the modern era, there are four prominent schools (madh'hab) of fiqh within the Sunni practice, plus two (or three) within Shi'a practice. A person trained in fiqh is known as a faqīh (plural fuqaha). Figuratively, fiqh means knowledge about Islamic legal rulings from their sources. Deriving religious rulings from their sources requires the mujtahid (an individual who exercises ijtihad) to have a deep understanding of the different discussions of jurisprudence. A faqīh must look deep down into a matter and not content himself with just the apparent meaning, and a person who only knows the appearance of a matter is not qualified as a faqīh.
