How should money obtained from an interest-based loan or a savings account in a usurious bank be purified, and what is the proportion for purification? Is it permissible to give this proportion as charity?

Opening a savings account in a usurious bank and borrowing from it with interest is haram (forbidden). The one who does so must repent and close the usurious account. The profits generated from this account must be disposed of by spending them on general Muslim welfare, such as the poor, the needy, and orphanages, with the intention of disposal, not charity. The account holder is entitled only to their principal capital. As for borrowing with interest, it is also riba (usury) and haram. The borrower must repent and resolve not to return to it. The borrower owns the loan because it has become a debt upon them, and they are not required to give any part of it as charity unless they choose to donate it voluntarily.
