It is narrated from Sayyiduna Zayd bin Khalid (may Allah be pleased with him) that a Bedouin came to the Prophet (peace and blessings be upon him) with a lost item. He (peace and blessings be upon him) said: "Announce it for a year, then know its tie and its pouch. If someone comes and tells you about it, give it to him; otherwise include it in your spending."
(b) In a narration from Sufyan: "If someone comes and tells you about its pouch and its tie, give it to him; otherwise spend it."
This wording is not in the narration of most of them, so it seems not to be preserved (ghayr mahfuz), as Abu Dawud said.
