How to fulfill the rights of those whose whereabouts are unknown

Question: A man knows that so-and-so wants a sum of money from him, and another so-and-so wants a sum from him, and another so-and-so wants a sum from him, but he does not know where they are after they changed their location? What should he do in this case? And is it permissible for him to give charity with a sum of money and make its reward for them? And what should he say in this case? We ask you to issue a ruling for us. May Allah reward you with good.

Answer: If he does not know their addresses, he should give charity on their behalf for their rights with the intention. When they appear or their addresses are known, if they accept the charity, the reward is for them. If they do not accept the charity, he gives them their rights, and the reward of the charity is for him. And success is from Allah.
