Musnad Ahmad Hadith 17060

It is narrated from Zaid bin Khalid (may Allah be pleased with him) that once he himself or another man asked the Prophet (ﷺ) about the ruling regarding a lost sheep. The Prophet (ﷺ) said: "You should take it, for either you will find it or the wolf will take it." The questioner asked: "O Messenger of Allah! What is the ruling if a lost camel is found?" The Prophet (ﷺ) became extremely angry, so much so that his blessed cheeks turned red, and he said: "What do you have to do with it? It has its water-bag and its shoes with it, and it can eat the leaves of the trees." Then the questioner asked: "O Messenger of Allah! If I find silver in a pouch, what do you command?" The Prophet (ﷺ) said: "Safeguard its container, its tie, and its count well, and announce it for a year. If its owner comes during that time, hand it over to him; otherwise, it becomes yours."
