Almost all institutions in Malaysia offering Islamic Studies in the field of Shari’ah make The Principles of Jurisprudence as compulsory course that must be taken by each candidate. This is due to the Principles of Jurisprudence dealing with crucial matters such as al-Dalil al-Ijmali (Comprehensive Proof), istinbat (derivation of rulings from nas (text) and debates related to ijtihad (the exertion of the utmost effort by a trained jurist).
