Notions of the social good including rights, fairness, and economic efficiency influence our choices of law and policymaking. The discussion on social good is normally a heated one in pluralistic societies with multiple worldviews on the right thing to do. This article brings a novel Islamic perspective on the social good in pluralistic societies. In doing so, it makes and defends three propositions: first, religious notions of the social good, including those derived from the Islamic worldview, should not be excluded from public justifications when making moral and policy choices. There is no good reason for plural/secular societies to reject the benefits of religious presence in public discourse given the overwhelming evidence on religious precepts being a mobilizing force to promote co-existence and social cooperation. Second, Islamic notions of social good can contribute to that end. The article criticizes the common perception of Islamic ethics that views Islamic doctrine as a rigid positivist system which imposes inflexible moral codes limiting the influence of independent human intellect and agency. I show that Islamic notions of the social good are dynamic and adaptable to change. The third part of the article shows that the social good in Islamic doctrine has always been defined with reference to essential human needs, including the promotion of life, intellect, social cooperation, and justice. At their core, Islamic notions of the social good exhibit an overarching deontological orientation towards moral choices. They broadly overlap with comparative and influential frameworks on human flourishing, including the ‘Human Development Paradigm’ and the ‘Capabilities Approach’.
