In their writings, Sadr and the other Shia authors "sought to depict Islam as a religion committed to social justice, the equitable distribution of wealth, and the cause of the deprived classes", with doctrines "acceptable to Islamic jurists", while refuting existing non-Islamic theories of capitalism and Marxism. This version of Islamic economics, which influenced the Iranian Revolution, called for public ownership of land and large "industrial enterprises", while private economic activity continued "within reasonable limits." These ideas helped shape the large public sector and public subsidy policies of the Iranian Islamic revolution.
