Revising the Sources of Identifying "the Good and the Evil" in Islamic Jurisprudence and Law

The good and the evil can be ethical, jurisprudential and legal and each of them will be identified through its specific criteria. There are various views among the experts about their sources of recognition. The main question is: what resources should be used to identify good and evil and whether there is a difference between these sources in jurisprudence and law? This paper, by examining five theories, defends a theory that differentiates Islamic jurisprudential good and evil from law-based good and evil. The findings of this paper proves that in jurisprudence, sources of recognizing the good and the evil, are religion and reason; but in legal terms, for the exclusive ways of identifying the good and the evil are the law, rules, and regulations.
