This differs from the DSN MUI fatwa No.73/DSN-MUI/XI/2008 concerning Musyārakah Mutanāqiṣhah. This study aims to determine the micro financing in BRISyariah KCP Majalaya, the mechanism and its relevance to the fatwa of DSN MUI No.73/DSN-MUI/XI/2008. The method used is descriptive, which is describing microfinancing with the musyārakah mutanāqiṣhah contract in BRISyariah KCP Majalaya. Based on the results of the study, it can be concluded that microfinance with the musyārakah mutanāqiṣhah contract is one of the products and services provided by BRISyariah KCP Majalaya. The mechanism starts with the customer submitting an application, before the disbursement the customer must pay the full cost, the customer then shares the profit accompanied by the purchase of a portion of the bank. The cost burden in conducting microfinance with the musyārakah mutanāqiṣhah contract is not yet relevant to the DSN MUI fatwa No.73/DSN-MUI/XI/2008, because all costs that should be borne jointly are borne by the customer, this can lead to injustice.
