If a Muslim becomes bankrupt, only the capital he lent should be taken from him

Q: Someone borrowed a sum of 25,000 SR from me in return for buying me a specific car (a certain model and options) after one year. However, this person became bankrupt, and many years passed and he could not pay his debt because of his poverty, so his brothers repaid the money instead of him. My question is: Is this considered Riba (usury), or does it contain any other doubtful matter? Is this deal permissible? Please support the answer with evidence. May Allah reward you.

A: There is no problem about getting your money back, and abdicating the Salam sale (sale with advance payment) of the car, that is, to exempt the borrower, or any person who repays the money instead of him, from buying the car, and there is no Riba involved in that.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
