The main question that this paper tries to answer it is to what extent the governors of Imam Ali played a role in economic security of the government? The findings are based on descriptive-analytical method and relies on statistical data, and, in contrary to the popular opinion, shows that most of governors of that Imam, with varying degrees of loyalty to the ideals of the Imam, played their roles in the economic security, and only thirteen percent of them betrayed and were punished accordingly.
