The Economic System of Islam by Taqiuddin an-Nabhani

International trade yields a tremendous benefit due to the high real profits which are generated from it. What adds to a person’s conviction about the importance of international trade is the ferocious fighting and fierce competition between the superpowers over the acquisition of new markets and the protection of old markets, to which their merchandise is disposed of, and from which they import raw materials without obstacle. International trade has a host of distinguishing features, merits and outcomes. The main reason behind the establishment of international trade is the disparity in the proportional costs of commodities between one country and another. It would therefore be in the interest of all countries to establish international trade between them once the proportional costs differed in each country.
