If the one who deals in riba repents from riba, what does he do with the money in excess of the principal?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: If the one who deals in riba dies, or if he repents from riba, what does he do with the money in excess of the principal?

Answer:
He deals with the money as follows: if it is in the hands of people, he leaves it there; if it is in the debts of debtors, he leaves it and does not collect it from them, taking only the principal of his capital, as Allah the Exalted said: However, if he has taken possession of it and received it, and then repents to Allah regarding it, he disposes of it by placing it in a general project from which people benefit. This is not in the category of voluntary charity, but rather in the category of disposing of it. Money that has no owner is placed in public utilities, and this is money that has no owner, so it is placed in public utilities and he disposes of it.
