what is fiqh in islam

Fiqh is the Islamic jurisprudence that deals with the human understanding and practices of the Sharia, which is the divine Islamic law as revealed in the Quran and the Sunnah. Fiqh expands and develops Shariah through interpretation (ijtihad) of the Quran and Sunnah. It deals with the observance of rituals, morals, and social legislation in Islam as well as the economic and political system. Fiqh is considered fallible and changeable, whereas Sharia is considered immutable and infallible. There are four prominent schools of fiqh within Sunni practice, plus two (or three) within Shi'a practice. A person trained in fiqh is known as a faqīh (pl.: fuqaha).
