The process of collecting and distributing funds has existed throughout history. In modern era, with the invention of credit money and the idea of capital in the capitalist system, banks were created to manage money and provide credit. Islamic scholars have offered different and sometimes opposing views on thismouseout="msoCommentHide('_com_1')" onmouseover="msoCommentShow('_anchor_1','_com_1')">[A1] mouseout="msoCommentHide('_com_2')" onmouseover="msoCommentShow('_anchor_2','_com_2')">[t2]  issue. Shahid Mohammad Baqer Sadr was one of the first Islamic thinkers to address this matter in an organized way. He saw the need for banks in Islamic society and proposed two models: 1-A non-usurious banking model for non-religious societies, and 2-An Islamic banking model for Islamic societies. Despite the importance of Islamic banking in Sadr's work, little research has been done on it. This article uses a qualitative approach and a simple method based on the seven-step model of Sandelowski and Barroso to explain Sadr's banking model. First, the general structure of governance was outlined, and then Sadr’s model for Islamic banking was developed. The research included all of Sadr’s writings on economics and banking, totaling 92 articles. After selecting relevant ones, 39 articles were analyzed. The findings show four main areas in Islamic banking governance: rules (six categories: multiple ownership, limited economic freedom, social justice, free zone, prohibition of hoarding wealth, and wages), laws (four categories: ensuring real value in loans, banning private banking, promoting state control, banning usury, and taxing accumulated assets), the incentive system, and the structure for public Islamic banking services.
