Signet Rings
Book Number: 029 / Hadith Number: 4210
Narated By Abdullah ibn Mas'ud : The Prophet of Allah (pbuh) 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.
