Musannaf Ibn Abi Shaybah 23003 — Lost property: what is to be done

It is narrated from Suwayd bin Ghaflah that he said: Zayd bin Suhan, Salman bin Rabi'ah and I set out on a journey. When we reached the place called al-Udhayb, I picked up a whip that had fallen. The two of them said to me: "Throw it away," but I refused. When I came to Madinah, I went to Sayyiduna Ubayy bin Ka'b (may Allah be pleased with him) and asked him about it. He (may Allah be pleased with him) said: "In the time of the Prophet (peace and blessings be upon him) I found 100 dinars. When I mentioned them to the Prophet (peace and blessings be upon him), he (peace and blessings be upon him) said: 'Announce them for one year. If the owner comes, hand them over to him; otherwise, take careful note of the number of the dinars, their container and its tie. Then it shall be like your own property.'"
