Jami` at-Tirmidhi, Volume 3, Book 13, Hadith 1374 (DarusSalam) ⓘ

Suwaid bin Ghafalah said: "I went out with Zaid bin Suhan and Salman bin Rabi'ah, and found a whip." In his narration Ibn Numair (one of the narrators) said: "I found a lost whip and took it. They said: 'Leave it'. I said: 'I will not leave it to be eaten by predators. I will take it to make use of it.' So I met up with Ubayy bin Ka'b and asked him about that. So he narrated the Hadith, he said: 'That is fine. I found a sack containing one hundred Dinar during the lifetime of the Messenger of Allah' He said: 'So I brought it to him. He said to me: "Make a public announcement about it for one year." So I announced it for a year but did not find anyone to claim it. Then I brought it to him. He said to me: "Make a public announcement about it for another year." So I announced it for a year but did not find anyone to claim it. Then I brought it to him. He said: "Make a public announcement about if for another year." And he said: "Remember its amount, its container and its string. If someone comes seeking it and informs you of its amount and its string, then give it to him, otherwise use it."
