Is it permissible to give one's wife and married sister from the usurious money that has been disposed of, and is it permissible to eat what is bought with this money if the beneficiary gives it as a gift?

It is not permissible to deposit money in a usurious bank except in cases of extreme necessity where no Islamic alternative is available. Usurious interests may not be spent on the wife for her obligatory maintenance, but it is permissible to give her from it to meet her non-obligatory needs, and likewise for a poor married sister. If these interests are paid to their rightful recipient and he takes possession of them, then it is permissible for the one who paid them to eat from what was bought with them, because a change of ownership alters the ruling on the money.
