The word fiqh is an Arabic term meaning deep understanding or full comprehension. Technically it refers to the body of Islamic law extracted from detailed Islamic sources (which are studied in the principles of Islamic jurisprudence) and the process of gaining knowledge of Islam through jurisprudence.n Modern Standard Arabic, fiqh has come to mean jurisprudence in general, be it Islamic or secular. It is thus possible to speak of Chief Justice John G. Roberts, Jr. as an expert in the common law fiqh of the United States, or of Abdel Razzaq El sanhouri Pasha as an expert in the civil law fiqh of Egypt.
