Question: Is it permissible to work in an organization which deals with usurious banks, knowing that the employee is the one who processes usurious loans?
Answer: “It is well known that an organization that deals with usurious banks is not [the same] as working at the bank [itself]. For working at the bank, in most cases, is built on usury. As for the one who deals with them, whether in an organization or otherwise, then if his work is not associated with usury there is no harm in him working in it” [https://m.soundcloud.com/tahawiya10/e0f5cykull2j]
