Is the money deposited by a father into his son's account, which was withdrawn from an interest-bearing bank account, considered usury for the son?

There is no harm in benefiting from money that a father transfers from his usurious account, and this money is not considered usury for the son, because the son deals with his mixed money, and that is permissible, with the obligation to advise the father to avoid usurious transactions and to seek out what is lawful.
