The Qur’an, as a source of Islamic law, undoubtedly has a profound influence on the legal system as a whole. In Islamic law, international law is governed by established principles intended to guide human life in a more structured and purposeful manner. Islam regulates relationships between individuals as well as between nations through principles developed within the Islamic tradition. These principles can be classified into the principles of justice, equality, and freedom. Islamic law accommodates international law through the concept of syiar (religious propagation or public expression of faith), as this area falls within the scope of ijtihadi (independent legal reasoning).
