Are earnings from working in a company whose capital consists of interest from deposits and commissions from cars prohibited?

This transaction is impermissible because the agent is entrusted and it is not permissible for him to benefit personally from the agency, and because the company deals with prohibited usury. The usurious interest must be disposed of by spending it on the welfare of Muslims. As for working in this company: if it involves direct engagement in usurious transactions or assisting them, then it is impermissible. If it involves permissible matters like cleaning and security, then there is no objection, although it is better to search for another job far from suspicion.
