Hazrat Anas (may Allah be pleased with him) narrated that the Messenger of Allah (peace and blessings be upon him) had a ring made and said, "We have had a ring made and the words (Muhammad Rasul Allah) are engraved on it, so no one should have this inscription engraved on their ring." Anas narrated that it is as if I can still see the shine of that ring on the little finger of the Messenger of Allah (peace and blessings be upon him).
