What is the ruling on working as a data entry clerk, receptionist, or salesperson in a company that sells cars in installments through a bank? Is this work considered unlawful (haram)?

Working at the aforementioned company in data entry and similar tasks is, in principle, not forbidden, as long as it does not directly involve unlawful acts or assist in them. If the employee encounters any such situation in their work, they must refrain from it and limit themselves to what is permissible. As for the transaction conducted by the bank, its nature is not sufficiently clear to rule upon it.
