Counterbalancing
    one another’s interest in the bank
Question

                Is it possible to counterbalance each other
      the interest of a borrowing by the winning interest of an investment in the same bank in
      order to avoid practicing usury and so taking advantage of different banking transactions?
Praise be to Allah.If it is proven that your friend has repented
    from riba and that he has a debt he owes and cannot pay, then you can get rid of the riba
    you have been given by giving it to him, otherwise do not give it to him.
