What is the ruling on settling old, accumulated debts stemming from interest on a financial deposit placed in a usurious bank?

It is not permissible to deposit money in usurious banks to accrue interest. If this has been done, then it is obligatory to dispose of these interests by spending them on the welfare of Muslims or distributing them among the poor and needy. It is not permissible to take from it except for the poor and needy person, to the extent of their need. One must hasten to pay off debts with available funds and strive to pay the remaining amount through permissible means.
