Ruling on taking a debt from a person whose wealth is forbidden

Honorable Shaykh! I lent one of our colleagues a sum of money, and he sold a car and bought a car with riba (usury or interest). He wanted to pay me back from the car amount,I asked him to pay me back from his salary, and he said: since it is all in one account number. Is it permissible for me to take it from him?
If you pressured him until you forced him to borrow, then it is forbidden for you. But if he came to you on his own to pay it off, then accept it, for this is your right, and you are not responsible for how he obtained it, whether through a forbidden or a permissible means.
