The quality of bayt al-mal distribution is one of the crucial issues in the Islamic system, and its fair distribution can create economic justice, public welfare, and social security in all strata of society. The present study aims to answer that Imam Ali's (AS) seerah in the administration of justice in the distribution of the bayt al-mal was based on which foundations and principles? To answer this question, the problem was investigated by reading the relevant books and in a descriptive-analytical way. In this research, after investigating the method of performance of Imam Ali (AS) in distributing the bayt al-mal, we concluded that Imam was able to direct the expenses of bayt al-mal with his unique knowledge. So, homogeneous economic growth was available in social classes, and this growth was not accumulated in a specific stratum. Imam aimed to grow all social classes and strongly avoided the concentration of wealth and the creation of social gaps. In this regard, Imam used to pay the shares of different classes of people from bayt al-mal equally according to their work criterion, need, and expediency.
