How is a lost sheep identified?

The questioner : In her second question, the questioner says over the phone: I am asking about a lost sheep. We said that it is to be identified for a year, and the hadith of the Messenger (peace and blessings be upon him) is: is it for you, or for your brother, or for the wolf?

The Shaykh : The hadith here does not specify the method of identification by the Messenger (peace and blessings be upon him).

The questioner : He said it is for you, meaning if you do not find its owner, or for your brother if you find him, or for the wolf if he does not find it and you do not take it, the wolves will eat it, because a sheep cannot defend itself. So, regarding the issue of identification? Regarding the issue of identification, it is said: there is no difference between a sheep and the dirhams about which the Messenger (peace and blessings be upon him) said:

The Shaykh : (peace and blessings be upon him).

The questioner : Identify its container and its tie, then identify it for a year. However, a sheep differs from dirhams, because if the one who finds it sees it in his interest to sell it so that it is not consumed by expenses, and he keeps its price for its owner if he is found, then he sells it after identifying its characteristics, writing its characteristics on a paper, and noting the time and place of its finding, so that when its owner comes and describes it, he gives him its value.
