Putting money in riba-based banks is a haraam action, and
there is no concession allowing it except in cases of necessity; in such

The riba or interest that is received from putting money in
the bank is riba which is haraam. Hence you have to get rid of it by

school. There is also nothing wrong if you give this interest to them to
spend it on their various needs, especially since they are poor and needy.
