The Ring of the Islamic Priest

This silver ring was found by my friend using a metal detector. At first we decided that this ring was made in the Middle Ages. But later we managed to consult with an old jeweler and translate the inscription on the ring, and then we realized that the ring belonged to an Islamic priest. Most likely, he lived in the late 18th and early 19th centuries. At the same time, this ring was lost. It is always interesting to find such ancient objects, but it is even more interesting to study what they served for and to whom they belonged
