What is the ruling on adult heirs borrowing from the money of orphaned heirs to repair a damaged inherited car, with a commitment to repay the money in the future, knowing that the one who caused the damage intended to trade with it for the benefit of the orphans? And what is the ruling on adult orphans participating in the repair of an inherited car that broke down due to disuse, and what is the ruling on those who did not participate in its repair benefiting from it?

If the accident occurred due to the driver's negligence, he is liable for the car and bears the cost of repair alone. If the adult heirs wish to donate towards bearing the cost of repair, there is no harm, but they are not permitted to donate from the minor's money. However, if the accident occurred without negligence on the part of the driver, he is not liable, and the cost of repair will be borne by the property of all heirs, both adults and minors, because a guardian is a trustee who is not liable for what perishes in his possession without negligence.
