Sacred Citation & SourceFiqh means understanding. The Prophet ﷺ said: "Whoever Allah wants good for, He gives him understanding of the religion" (Bukhari 71, Muslim 1037). In the technical sense, fiqh is the knowledge of practical rulings (prayer, fasting, trade, marriage and so on) drawn from their detailed evidences. Usul al-fiqh is the science of the principles and methods by which scholars draw those rulings: which sources are valid, how a text is read, and what to do when texts seem to differ. Allah says: "Ask the people of the Reminder if you do not know" (16:43). Usul al-fiqh does not invent a new religion; it is the discipline that keeps understanding orderly and consistent. Learning it helps a believer see why qualified scholars can reach different views without one of them leaving the faith.
