What is the ruling on receiving financial dues from a company that dealt with usury, after leaving employment there, with the aim of getting rid of debts and providing for one's family?

Working in usurious institutions is forbidden because it is a form of cooperation in sin. As for one who repents, he may take his entitlements, not as an act of ownership, but rather to be spent on the general welfare of Muslims. Debts should be paid off from it, and it should not be spent on the expenses of relatives or wives as long as the provider possesses what he can spend on them.
