Q 5: What is
the ruling on working for an organization or company that deposits and withdraws from bank accounts and takes Riba (usury/interest)-bearing loans from banks?
It is not permissible to work for such a company, because it involves cooperation in the Haram (prohibited) things. Allah (Exalted be He) says (what means):
...but do not help one another in sin and transgression.
