Giving Usurious Benefits to Poor Sisters

Question
Two sisters, one is poor and the other is a widow, their brother gave them a large amount of bank interest, which they spent on their children. Later, they learned that it was bank interest and that it is forbidden. Do they bear a sin, and is it necessary for them to gather the amount and remove it from their obligation even though it is difficult for them to collect this money?
Answer
I say, and with God's success: Bank profits are from illicit earnings that the owner must give in charity, and it is permissible for the recipients to benefit from it, and the two sisters are not required to return it, and God knows best.
