The ruling on one who does not know the owner of a debt and wants to give the debt in charity

Question:
The listener Abdullah Qasim al-Sayyid sent a question, saying: I took a sum of money from a person, and I do not know where he is now. I want to give this amount in charity. Is it permissible for me to give it in charity to my relatives, and will he get the reward?

Answer:
Yes, there is nothing wrong with giving it in charity. If he permits it, and if not, return it to him when he appears and claims his right. If he permits the charity, he gets the reward. If he does not permit it, the reward is for you, and you must give him his money. Yes.

The presenter : May Allah reward you with good and do you good.
