Is the Prophet's — may God’s prayers and peace be upon him — naming of his possessions, such as his mule "Duldul," his sword "Al-Battar," and his turban "Al-Sahab," considered a forgotten Sunnah?

The Prophet, peace and blessings be upon him, used to name his possessions with special names, such as his donkey "'Ufair" and his horse "Mandūb," in line with the custom of his people to distinguish them and facilitate their retrieval, not as an act of worship. This indicates the permissibility of naming animals and possessions with special names, and that it is not intended for legislation or worship, but rather it is among the permissible natural acts.
