In Islam, men are forbidden to wear jewelry made of gold, silver, or any other substance, except for a plain silver ring which is permissible. Ali bin Abi Talib narrated that (meaning):
“The Prophet of Allah [SAW] took hold of some silk in his right hand and some gold in his left, and then he said: ‘These two are forbidden for the males of my Ummah (Muslim Nation).'” [Source: Sunan an-Nasa’i no. 5144]
In other hadith, Ibnu Umar narrated that (meaning):
“Allah’s Messenger (ﷺ) wore a gold ring or a silver ring and placed its stone towards the palm of his hand and had the name ‘Muhammad, the Messenger of Allah’ engraved on it. The people also started wearing gold rings like it, but when the Prophet (ﷺ) saw them wearing such rings, he threw away his own ring and said. “I will never wear it,” and then wore a silver ring, whereupon the people too started wearing silver rings. Ibn `Umar added: After the Prophet (ﷺ) Abu Bakr wore the ring, and then `Umar and then `Uthman wore it till it fell in the Aris well from `Uthman.” [Source: Sahih al-Bukhari no. 5866]
Men’s jewelry is subject to zakat if it reaches nisab, which is 85 grams of gold or 595 grams of silver, because the use of jewelry by men is not considered a satisfaction of a natural need, like that of a woman.
Zakat is obligated on men’s jewelry as a reminder of the error of owning it and of the need to put its value back into productive use.
As for gold used by men, it is prohibited completely, except for such necessities as, caps for teeth, toot filling, or as a substitute for a cut nose or a cut ear.
There is one hadith (meaning):
AbdurRahman ibn Tarafah said that his grandfather Arfajah ibn As’ad who had his nose cut off at the battle of al-Kilab got a silver nose, but it developed a stench, so the Prophet (ﷺ) ordered him to get a gold nose. [A hasan grade hadith (Albani). Source: Sunan Abi Dawud no. 4232]
Any other use of gold, as an ornament or such, by men, is forbidden and is subject to zakat. We should recognize, however, that it is preferred to consider value, and not only weight, in the case of men’s jewelry. This is because of the value added by the artistic labour. Once the value of this jewelry reaches the equivalent of nisab (85 grams) of gold it becomes subject to zakat.
For example, if the weight of gold within a year is 200 grams then:
= Gold Weight x Current Gold Price (1 gram) x Zakat Rate (2.5%)
= 200 grams x RM170 (example) x 2.5%
