Is it permissible to take money distributed by the non-Muslim ship captain from the sale of fuel saved without the company's knowledge, given that this money is part of a black market operation, and that the salary received from the company is much less than what is due, taking into consideration that refusing the money causes problems with the captain? Is it permissible to take it with the intention of donating it to the poor to avoid problems?

What the captain is doing is an act of aggression and an unlawful taking of company money. He should be advised, and if he does not respond, the company should be informed, provided that it does not cause severe harm to the questioner.

As for taking what the captain offers, it is not permissible unless it is to be returned to the company. If returning it is not possible, then it is permissible to take it to spend on the poor and needy, rather than leaving it in the hands of the usurper, while condemning his action.

Regarding the salary, if the questioner agreed to an amount less than what he deserves, then he is only entitled to the agreed-upon amount.
