Getting rid of riba by giving it
    to the poor
Question

                Can we give the interest from banks to the
      needy one?
Praise be to Allah.If there is a person who deals in riba (interest/usury),
    then repents and wants to get rid of the money he gained from riba, it is permissible for
    him to give it to the poor in order to get rid of it. A person can also do likewise if an
    amount of riba is put into his account by the bank, but this is not counted as sadaqah
    (charity), because Allaah is Good and only accepts that which is good and pure. As for
    continuing to deal in riba, this is not permissible, because it is one of the major sins
    (kabaa’ir), and taking it is tantamount to challenging Allaah and His Messenger, even
    if one is dealing in riba in order to give it to the poor.
