Is it obligatory to give in charity the money earned from selling workers' visas?

Selling visas is impermissible. The money obtained from it has a detailed ruling: If it was taken from the worker who was brought in, it must be returned to him while he is alive or to his heirs after his death. If it is impossible to reach them after exerting effort, it should be given as charity on his behalf for the general welfare of Muslims. If he or his heirs are later found, they are given the choice either to approve the charity given on their behalf or to reclaim the money. However, if the money was taken from companies or brokers, it should not be returned to them; instead, it should be spent on charitable causes. The Permanent Committee has issued a fatwa stating that selling visas is impermissible because it involves lying, deception, and unlawfully consuming people's wealth. The money earned through this method is illicit gain that must be disposed of by spending it on good and charitable causes. As for money taken from the workers themselves, it must be returned to them; if that is not possible, it should be given as charity on their behalf.
