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 (ﷺ)' 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.
