Is it forbidden for a wife to work as an employee in a bank that deals with interest-bearing loans, and are the husband, the wife, and everyone who deals with these banks sinful, and are the funds acquired from the government, which relies on suspicious sources, forbidden?

It is not permissible to work in interest-based banks, including the bank mentioned, because it constitutes cooperation in sin and aggression, which is forbidden by His Almighty's saying: "And do not cooperate in sin and aggression." The husband must prevent his wife from working there, in accordance with His Almighty's saying: "O you who have believed, protect yourselves and your families from a Fire." The fact that an employee's salary comes from suspicious funds does not justify working in an interest-based field.
