A month back a friend of mine found some money on a road when he was walking there. He tried to search for the owner of the amount, but all in vain. He took the money with him and continued his search for many days but he failed to find the owner of the money. Now on the behalf of my friend I request you to guide me and my friend in this matter. Can he use that money for his own benefit, if so, how should he use the money so that he would not be committing a sin?
