Market has always been part of development in Indonesia and in any country in that matter. How far development will succeed depends very much therefore on the nature of market. Well-managed market will certainly affect the process of development. This paper deals with the relationship between market and development with particular attention to the notion of justice. It argues that in Indonesia economic injustice is the main cause for the failure of development for many decades. The paper tries to show the many indicators of that injustice which includes among others, the unequal distribution of wealth among the citizens. The paper then moves to the economic system of Islam which –it argues- is based on the concept of justice, and maintains that this Islamic system can be both the solution and alternative for the ailing Indonesian economy.

Many methods can be used in measuring company finances, including Islamic Commercial Banks. Maqashid Sharia Index (MSI) is a measuring tool in calculating the Financial Sustainability Ratio (FSR). This study aims to measure the FSR of Islamic commercial banks using the MSI measuring instrument method. The results will see the extent to which MSI can calculate the FSR of Islamic retail banks. MSI also estimates how far MSI is connected to the FSR. The method used in this research is descriptive quantitative research. The data obtained is in the form of secondary data. The data is compiled based on the financial reports of BUS that are registered with the OJK from 2012 to 2020. Sampling was done using the purposive sampling technique. The data collection technique uses the documentation method. The analysis used includes regression test, partial test, ANOVA test, and coefficient of determination. The results showed that MSI has a positive effect on FSR. MSI also provided information that the FSR provided positive results for Islamic commercial banks by being aware of the ummah's problems.
