The Messenger of Allah ﷺ had a ring made of silver, and he had engraved on it "Muhammad, Messenger of Allah." Then the Messenger of Allah ﷺ said, "I have had a silver ring made and engraved on it 'Muhammad, Messenger of Allah,' so let no one else engrave the same on his ring."
حدثنا يونس حدثنا حماد يعني ابن زيد حدثنا عبد العزيز بن صهيب
أن رسول الله ﷺ اتخذ خاتما من فضة ونقش فيه محمد رسول الله فقال رسول الله ﷺ إني قد اتخذت خاتما من فضة ونقشت فيه محمد رسول الله فلا تنقشوا عليه
