Is it permissible to benefit from 44,0 in unlawful bank interest to cover household needs and expenses, knowing that the husband is in severe financial distress, or must it be disposed of by giving it to charities?

The usurious bank interests are not permissible for the depositor to benefit from, unless he is poor and in need, in which case it is permissible for him to take what suffices his needs from it. If the questioner is in need of her necessities, she may take what suffices her needs from it and spend the remainder on general Muslim welfare, such as reliable charitable organizations.
