Getting rid of riba by giving it to the poor

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.
