The Gold Dinar/Islamic Dinar is studied as a currency that mobilizes financial resources into Islamic-compliant ends within a general-system approach to complementary relations between money, finance, and the real economy. Thus, a 100 Percent Reserve Requirement Monetary System (100%RRMS) is formalized in the context of the gold standard that mobilizes resources and stabilizes currency value within the money, finance, and real economy complementary relations. Such complementary relations are established by circular causation based on the Islamic episteme of unity of knowledge applied to systemic relations. Unity of knowledge as the episteme ultimately arises from the unity of the divine law (Tawhid). Upon this epistemic arguments stand the reasoning and formalism of the Islamic socio-scientific entirety.
