The ruling on the money of one who repents from riba (usury or interest) and how he disposes of it

Question:
He says: Honorable Shaykh, may Allah grant you success. Some people, quoting from one of the students of knowledge, say that the one who repents from riba (usury or interest) is entitled to his principal capital that he has with him now. Because if you tell people to dispose of the money they earned through riba (usury or interest), they will not obey you. But if you tell them that they may keep their principal capitals that they have with them now, they will stop dealing in riba (usury or interest). What is the ruling on this?

Answer:
It is not clear. If he takes only his principal capital, that is what Allah said: "Take our wealth." But if he intends to keep the riba (usury or interest) profits he has received as his own, that is not permissible. Even if he has received the riba (usury or interest) profits, they are not permissible for him to keep. However, disposing of them means he places them in one of the public projects and disposes of them, and repents to Allah, so that in the future he does not deal in this matter. As for saying to him, "Take the profit and own it, and repent to Allah," he says: No, this is not a matter of reconciliation. Riba (usury or interest) is forbidden, so it is not permissible for a person to take it, possess it, and own it. And to say, "If the garment is sufficient," this is not permissible. Yes.
