Getting rid of riba (usury or interest) money upon repentance

Question:
Honorable Shaykh, what is the ruling on a man who accumulated his wealth through riba (usury or interest) and dealing in it, starting with an amount of one thousand riyals, and his wealth became fifty thousand riyals after dealing in riba? If he repents, what is required of him? Does he give in charity the riba money he has and keep his principal?

Answer:
If he took possession of the riba, if he took possession of the riba and repented to Allah, he should place it in one of the public projects to get rid of it, because it is money that has no rightful claimant and no owner, so it is placed in what has no owner, namely public projects. This is if he took possession of it. But if he did not take possession of it, it is not permissible for him to take it; he does not withdraw it from the one who has it, but he takes only his principal. If you repent, then for you is your reward and your wealth. Yes.
