What can a person do with usurious money (Riba); should he donate it as charity or what?

Money acquired through usury must be spent on the poor, the needy, and for the general welfare of Muslims, with the intention of getting rid of it. It is not permissible for the one who acquired it or his relatives who benefit from his spending to claim ownership of it. It is not permissible to engage in usurious transactions or to deposit money in usurious banks except in cases of extreme necessity. In such a case, the money should be placed in a current account; if unavailable, then in a savings account, provided that the usurious interest is disposed of.
