Buraida reported the Prophet as saying to a man who was wearing a signet-ring of yellow copper, “How is it that I notice the odour of idols in you ?” So he threw it away and came wearing an iron signet- ring, and when he said, “How is it that I see you wearing the adornment of the inhabitants of hell ?” he threw it away and asked God’s messenger what material he should use. He replied, “Silver, but do not let it weigh as much as a mithqal.”
Tirmidhi, Abu Dawud and Nasa’i transmitted it. Muhyi as-Sunna said there is a sound tradition on the authority of Sahl b. Sa'd about the dower that the Prophet said to a man, “Seek something, even though it should be an iron signet-ring.”
Narrated Ibn Mas'ud said there were ten things the Prophet disliked:
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 invocations, except with the mu'awwidhat (The last two suras of the Qur'an are known as al mu’awwidhatan. Here the plural is used, and the suggestion is made that it may include certain supplications and prayers using names of God ; or that suras cxii and cix may be added to the last two), wearing amulets, withdrawing the penis before the semen is discharged, and having intercourse with a woman who is suckling a child; but he did not declare them to be prohibited.
Abu Dawud and Nasa’i transmitted it.
‘Ali told that the Prophet, taking some silk and putting it in his right hand, and taking some gold and putting it in his left hand, said, “These are prohibited to the male members of my people.”
Ahmad, Abu Dawud and Nasa’i transmitted it.
