The mosque is a place of worship for the Muslim community. Apart from being a place to pray, mosques are also often used as a place to hold religious activities and other social activities such as TPA, breaking fast together, qurban, management meetings, and taklim majlis. Because of the many positive and religious activities that can be held in a mosque, this can be a trigger for the enthusiasm of the mosque congregation, the society or donors to support activities carried out by setting aside some of their assets by providing assistance in the form of money, food. and other forms. Every mosque congregation, the general public or donors who have submitted the assistance that has been distributed, of course, wants what has been submitted to the mosque management to be allocated to things that are useful and in accordance with what they have been entrusted with. Therefore, all parties with an interest in the accountability report for the management of mosque funds expect that they will receive a report whether directly announced every Friday or indirectly, such as a list of receipts and expenditures of funds that is displayed on the mosque wall.
