Some people donated money to treat a sick person. After the treatment was over, there was a sum of money left enough for him to perform ‘Umrah. Is it permissible for him to perform ‘Umrah with this money?

All perfect praise be to Allaah, The Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.

If the donors intended to transfer the ownership of money to that sick person and console him with it, he is permitted to perform ‘Umrah with the rest of the money after treatment. But if they intended that he uses the money for treatment only, he is not allowed to spend it in any other purpose unless he seeks their permission. If they allowed him to perform ‘Umrah with the money, it is permissible for him to do so; otherwise, he is required to give the money back to them.
