It was narrated from Anas that: The Prophet SAW had a ring and he said: "We have had a ring made with an inscription, and no one else should copy this inscription". It is as if I can see its shining on the little finer of the Messenger of Allah SAW.
The Prophet [SAW] wore his ring on his little finger which shows how much he valued it and cherished its uniqueness. This teaches us to value our possessions and take care of them with love and respect.
Overall, this hadith emphasizes the importance of being original in our thoughts, actions, words etc., valuing our possessions as well as appreciating uniqueness in ourselves or others around us.
