What is the ruling on the money the son received after reaching the age of twenty-five, given that the Ministry of Social Insurance continued to send him the pension despite his request to stop it? Can he spend it on the welfare of Muslims to clear his conscience, or is the money considered a debt upon him, knowing that he has already spent it and nothing remains of it?

The pension received by a son after exceeding the permissible age is not lawful for him to take. The son must inquire from the Ministry why the pension was not stopped. If it was with their knowledge and consent, then there is no harm in him benefiting from it. If not, he must return it to the Ministry. If he is unable to do so, he should spend it on charitable causes and public welfare. He may also benefit from it if he is in need.
