The ruling on one who has a debt and cannot find its owner

I bought fruit from a vendor in front of one of the grocery stores, and when I paid the bill, I found that the money I had with me was not sufficient. The vendor asked me to bring the remainder another time. When I returned to the vendor's location after a period of time, I did not find him. I asked the owner of the grocery store, and he said that he had left selling with him and does not know his whereabouts. The grocery store owner refused to accept the amount from me. Now I ask how I should deal with this debt whose owner I cannot find?
Answer: If a person has a debt and does not know the owner of the debt, for example: he moved to another place or traveled, and likewise if he had a deposit or a loan with him and its owner left and he did not know about him and did not know him, then after investigating and after exerting the possible effort to identify him or his location, if he is unable to do so, he waits the appropriate period in case his owner comes to him if he knows him. If he does not come, he gives it in charity to the poor and the needy, or he spends it on some charitable projects, such as building mosques and restrooms and the like of such charitable projects, and the reward is for its owner. He intends it on behalf of its owner, the owner of the money, and Allah will convey the reward to him .
But if he waits for some period in case he comes, that is good from the standpoint of caution. Then if the owner of the right comes, he has the choice: if he wishes, he accepts the charity and it becomes his charity, and if he wishes, he demands his right, so you give him his right, and the reward is for you in what you gave in charity. Yes.
