One of the most important functions of social monotheism is its role in the reconstruction of Islamic civilization. The idea of ​​monotheism as a social doctrine by Ayatollah Khamenei, as well as the necessity of total servitude to God in the maximum form, strengthens the hypothesis of the role of social monotheism in the reconstruction of Islamic civilization. In order to prove the above hypothesis, this paper aims to show the output of the social reading of monotheism in the theoretical foundations of the process of civilization reconstruction, and explain its requirements, focusing on the Qur'an and the thoughts of Ayatollah Khamenei. As a result, both instrumental and main parts of the new Islamic civilization find a new color with the social reading of monotheism. The ideology of this civilization is the social faith and its centrality is the ummah (nation) and the transgeographic monotheistic society, and its leadership is carried out by the innocents and their representatives in a continuous and transhistorical manner. The requirements are political, social and economic system-building based on social and dynamic jurisprudence around monotheism and its proliferation, accumulation of social will based on monotheistic agency and activism, and a critical look at non-monotheistic and ineffective civilizations.
