Lack of Rational Reasoning in Normalizing the International Rules

The true resources of law stem from culture, religion, race, language, and human civilization. However, formal resources only pass the legislative process. In domestic law of countries, because there is only one governance, the law resources are regulated according to the conditions of each society. But in international law, we are faced with different governments and rulers. This research aims to determine the capacity of "Islamic Jurisprudence" to meet the "common legal resources" of the countries. The method used in this research is a descriptive-analytical method. The studies show that in the meantime of establishing formal resources of the international law, according to the article 38 of the statute of International Court of Justice, only the international treaties, international custom, general principles of law, international judicial procedure, doctrine, and justice have been considered. And the rational reasoning and independent intellectual rules have not been addressed. It is concluded from the results of the research that achieving international peace and security requires that the countries have proper interaction with each other. One of the most important contexts to meet this interaction is the "Theory of independent intellectual rules" and considering the role of wisdom in establishing international legal rules.
