The holy Quran has put “calling people to do good deeds” [or calling people to an act of benevolence] besides and prior to “commanding rightand forbidding wrong”, [or commanding beneficence and forbidding maleficence]. However in many interpretive and jurisprudential books, no sufficient effort has been made to elaborate the difference features between these two and their results, whose manifestation is observed in indifference attitude of legislative system to determine the limits, terms and qualities of ‘ call people to do good deeds”, despite the emphasize of the Eight Principle of the Constitution. Exploring the mentioned sources, this paper is an attempt to deal with the concept, dimensions and examples of “call people to do good deeds” such as propagation, teaching and advice which both have originally a basic role in cultural policy-making and institutionalization in the country and also due to paving ground for the fulfillment of “commanding rightand forbidding wrong” is of great significance. Then, it will clarify the distinctive points between these two hypotheses, so that the way to determine the base and policy will be cemented for the institutions with common functions (such as IRIB and supervising institutions such as Supreme Council of the Cultural Revolution) or specific of one of these two ( such as Law Enforcement and Assembly of Experts). Moreover, it will help with the preparation of grounds for the next researches on basic and performance pathological study of these institutions and policy-making on this issue as well.
