Sharia Financial Institution is an institution that is engaged in serving the needs of the community or customers in the economic and banking sectors. This paper explores the importance of sharia compliance aspects in mudharabah and musyarakah contract products. The objective to be achieved in this paper is to describe to the public, especially sharia banking stakeholders, the importance of sharia bank activities, especially mudharabah and musyarakah contracts that are guided by Islamic rules in their business. The literature used in this study comes from literature studies that refer to books, the internet and journal papers that have the same topic as the discussion being studied. The results of the study explain that the Sharia Supervisory Board (DPS) has an important role in realizing mudharabah and musyarakah contract products based on sharia aspects. This is implemented in the form of serious supervision and monitoring in accordance with the main functions and duties of the DPS itself. By doing so, it is hoped that public trust will continue to grow and develop so that their confidence to continue to believe and be loyal to Islamic banks will be maintained.
