Sunan Abi Dawud Book 36, Hadith 8
Ziyad b. Sa'd, Shu'aib and Ibn Musafir transmitted it from al-Zuhri. 'Ali said in their versions: "of silver".
They searched for it but could not find it. 'Uthman then fashioned a signet-ring and engraved on it "Muhammad, the Messenger of Allah". He used to wear it or stamp with it.
The Prophet of Allah (ﷺ) disliked ten things: Yellow colouring, meaning khaluq, dyeing grey hair, trailing the lower garment, wearing a gold signet-ring, a woman decking herself before people who are not within the prohibited degrees, throwing dice, using spells except with the Mu'awwidhatan, wearing amulets, withdrawing the penis before the semen is discharged, in the case of a woman who is wife or not a wife, and having intercourse with a woman who is suckling a child; but he did not declare them to be prohibited.
Abu Dawud said: Only the transmitters of Basrah have transmitted this tradition.
