Is it permissible for me to dispose of an amount of 500 dinars of unknown origin that has been in my financial account for 3 years, and no one has claimed it, after both institutions I worked for confirmed that they were not the source, and the postal service stated that it is likely to be a social security disbursement?
If you investigate the source of the amount and it turns out to be from social security, there is no harm in you benefiting from it, provided that social security is Islamically permissible. If it later becomes clear that it was deposited into your account by mistake, you must guarantee it to its owner.
