--- - |2 Abstract The Islamic conception of social exclusion complements the Catholic perspective found in other contributions to this issue. The Islamic prohibitions of social exclusion are derived from theological principles that combine to provide a metaphysical basis for the golden rule that one should treat others as one wishes to be treated. This article examines the roots of a practical morality that enjoins us to treat other people as equals and prohibits exploitation of them in economic exchange. This philosophy is based on four principles found in the Qur'an and the hadith (teachings of the Prophet): vicegerency, commensurability, responsibility, and prophecy. These four principles combine to show how humans, as God's agents on earth, have the means to carry out the divine will. The practice of justice in Islamic thought does not rely on social conventions that are variable and contingent but on absolute principles revealed to us by the Prophet. That gives Islam an advantage over secular thought in establishing a strong foundation for social and ethical principles that give egalitarianism a transcendent basis. Thus, social inclusivity in Islamic thought is an integral part of a life governed by piety and prophecy. - 'American Journal of Economics and Sociology, Volume 78, Issue 4, Page 895-922, September 2019.
