It is narrated from Sayyiduna Zayd bin Khalid al-Juhani (may Allah be pleased with him) that a man asked the Messenger of Allah (peace and blessings be upon him) about a found item, and he (peace and blessings be upon him) said: "Announce it for a year. Then recognise its container and its tie well. Then include it in your spending. If its owner comes, give it to him." He said: "O Messenger of Allah, what is your view about stray sheep?" He (peace and blessings be upon him) said: "They are for you, or for your brother, or for the wolf." He said: "O Messenger of Allah (peace and blessings be upon him), what is the ruling on a stray camel?" The Messenger of Allah (peace and blessings be upon him) became angry, until his (peace and blessings be upon him) blessed face turned red, and he (peace and blessings be upon him) said: "What have you to do with it? It has its hooves and its water supply with it, until its owner finds it."
