Narrated by Zaid bin Khalid
A bedouin asked the Prophet about the Luqata. The Prophet said, "Make public announcement about it for one year and if then somebody comes and describes the container of the Luqata and the string it was tied with, (give it to him); otherwise, spend it." He then asked the Prophet about a lost camel. The face of the Prophet become red and he said, "You have o concern with it as it has its water reservoir and feet and it will reach water and drink and eat trees. Leave it till its owner finds it." He then asked the Prophet about a lost sheep. The Prophet said, "It is for you, for your brother, or for the wolf."
