As far as Islamic Shari`ah is concerned, men are prohibited to wear golden adornments irrespective of whether those golden adornments are made of white gold or not. In other words, we can say that all types of gold -i.e. natural and pure gold- are forbidden for men. They are permissible for women. Men are allowed to use silver but not gold.
Dr. Muzammil Siddiqi, former president of the Islamic Society of North America (ISNA), states the following: There are a number of hadiths that indicate that the Prophet (peace and blessings be upon him) forbade the males of his Ummah from wearing pure golden jewelry and pure silken garments.
Besides, the jewelry the Muslim jurists also forbid men to use golden pen, golden watches, gold cigarette cases and lighters, golden cutlery. All these things are forbidden, unless the amount of gold in them was insignificant or they were not golden, or gold-plated with a very small amount of gold.
There are many hadiths on this subject. For example, it is reported by ‘Ali (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) took some silk in his right hand and some gold in his left hand and then he said, “These two are haram for the males among my followers.”
(Reported by At-Tirmidhi and An-Nasa’i)
The aforementioned hadith do not make any distinction between the yellow gold and the white gold.
Since the general word “gold” is used, we can say that all types of gold -i.e. natural and pure gold- are forbidden for men. They are permissible for women. Men are allowed to use silver but not gold. This is the command of Allah and it is given to us through the Prophet (peace and blessings be upon him). We should observe all the commands whether they are in the Qur’an or in the authentic Sunnah.
