Abdul Warith bin Sa'id bin Dhakwan عبد الوارث بن سعيد بن ذكوان · The Book of Adornment

The Prophet said: "The Jews and Christians do not dye their hair, so be different from them."

"The Messenger of Allah forbade me from four: Gold rings, wearing Al-Qassi, reciting Qur'an while I am bowing, and from wearing garments dyed with safflower."

The Prophet forbade gold rings.

He saw a ring of silver on the hand of the Messenger of Allah threw his ring away and the people threw their rings away too.
