Usul al-fiqh II is a course on Islamic jurisprudence. It covers secondary sources of law such as istihsan (juristic preference), istislah (public interest), and turuq istinbat (methods of derivation). The course aims to describe principles of Islamic law and help students apply them to contemporary issues. Assessment includes tests, presentations, class participation, and a final exam. Istihsan allows setting aside an existing legal analogy if upholding it would go against ideals of justice or public interest. Proponents argue it prevents rigidity and incorporates flexibility, though some jurists reject it as relying too much on personal opinion.
