: The Political Configuration of the Shariah Banking in Indonesia. Islamic law applies to Muslims wherever they are, whatever their nationality. But the National law is the law applicable to a particular nation, in a particular national state. In Indonesia's case, the National law also means the law developed by the Indonesian people, after Indonesia became an independent country and in force for the Indonesian people as successor to the old colonial law. Thus, Islamic law should be used now instead of the colonial law, which is no longer relevant to Islamic values. Shariah banking law is a product of National law which is adopted from Quranic and Sunnah values. Therefore, in the realm of business law, the Islamic law is a truly National law.
