The word Halal is part of a complex lexical and a conceptual system that is particularly refined in its more authentic and articulated configuration. The opposition between Halal (allowed) and Haram (not allowed) creates a broad area within which there are many intermediate words, such as, for example, Makruh (inadvisable) and Mubah (admissible), which allow one to contextualise the various forms of behaviour regarding an inclination to contribute positively or negatively to a relationship of a complex physical and spiritual order in both individuals and communities. Leaving aside the aspect usually addressed, that of vetoes concerning some types of meat or drinks, this system of precepts is best addressed from a theological perspective in which the believer is called upon to elaborate ways in which the best use of oneself can be made, in view of a more active and successful obedience to divine will.
