Sayyiduna Abdullah bin Amr bin al-As (may Allah be pleased with both of them) narrates that a man from the Muzaynah tribe came to the Noble Prophet (peace and blessings of Allah be upon him) and said: “What do you say about something found on a public road or in a populated settlement?” The Prophet (peace and blessings of Allah be upon him) said: “Announce it for one year. If its seeker comes, hand it over to him; otherwise, use it for your need. If at any time its owner comes to claim it, give it to him. And whatever is found on a deserted path or in an uninhabited settlement, then one-fifth must be paid from it and from buried treasure.”
