Some of the theologian subjects have direct effect on jurisprudencial deductions. The comprehensiveness and perfection of Divine laws is one of the theologian subjects affecting the religious texts directly and immediately. Under Free-Will statement, religion is for the felicity of man in this world and in the Hereafter. Based on the religion comprehensiveness and under this insight, the interpretable religious texts are interpreted in this trend.This paper seeks to investigate that Islam has considered both the general and specific principles in this concern, but imposing such laws and rules does not mean that these laws are enough to cover all aspects of life, so it is necessary to impose certain needed laws based on Divine Laws.The paper then goes on to study one of the important results concerning the divine laws perfection and comprehensiveness including religion towards the government and administrative organs. But the acceptance of this statement does not mean to establish all the govermental rules and principles, while the divine law is able to acknowleddge certain intellectual rules and principles and to reject others, and to comment its own viewpoint.
