What is the ruling on working with mixed wealth, such that most of the money is lawful, with the presence of unlawful money that can be identified and given away in charity?

It is permissible to work and earn a lawful living in a company whose funds are mixed, as long as the worker's job is permissible and has no relation to the company's forbidden transactions. As for working in a company where lawful and forbidden activities are mixed (such as selling prohibited items), it is permissible if the worker does not directly engage in or assist with the forbidden activities. However, if he directly engages in them or assists with them, then it is forbidden, except in cases of dire necessity or extreme need, and in such a case, he must then dispose of the unlawful earnings.
