Use of a country house for personal or commercial purposes without valid permission may be unlawful. However, businesses run by families of TNI soldiers with permission from the Head of the Dormitory and approval from the Military Command are considered legal, as long as they do not change the physical shape of the dormitory and do not interfere with TNI duties. From an Islamic legal perspective, TNI dormitories are milk al-daulah or state property which must be managed for the public benefit and must not be misused for personal gain. The use of TNI dormitories for private businesses managed by the families of TNI soldiers can provide positive benefits for the surrounding community, but must always comply with applicable legal provisions so as not to violate the principles of fair management of state property and milk al-daulah.
