After having presented the definition of Usool ul-Fiqh in the first chapter; its origins, history, men, methods, paths and its books, we now move on to the most important of its subject areas and this is the subject of the Adillah Al-Ijmaaliyah, which are the sources of the Islamic legislation and from which the practical Shar’iyah rulings are derived.
