Bulugh al-Maram #1090

Narrated Zaid bin Khalid al-Juhani (RA): A man came to the Prophet (ﷺ) and asked him about an item found (in the street). He replied, "Note what it is contained in, and what it is tied with, and make the matter known for a year. Then, if its owner comes (give it to him). Otherwise, you can do what you like with it." He asked, "What about astray sheep?" He replied, "It is for your, your brother, or the wolf." He asked, "What about astray camels?" He replied, "What have you to do with them? They have their stomachs and their feet. They can go down to water and eat trees till their master finds them." .
