In the name of Allah, the Most-Merciful, the All-Compassionate
As-Salaam Alaikum Wa-Rahmatullahi Wa-Barakatuhu
"May the Peace and Blessings of Allah be Upon You"
Praise be to Allaah, we seek His help and His forgiveness. We seek refuge with Allaah from the evil of our own souls and from our bad deeds. Whomsoever Allaah guides will never be led astray, and whomsoever Allaah leaves astray, no one can guide. I bear witness that there is no god but Allaah, and I bear witness that Muhammad is His slave and Messenger.
Major Sins #56: Men Wearing Silk or Gold - By Imam Dhahabi
In the two Sahihs, the Messenger of Allah (pbuh) is reported to have said, "He who wears silk in this worldly life, will not wear it in the Hereafter.” [Reported by AI-Bukhari]
This is a general rule which applies to all classes of people, whether soldiers or otherwise. The Prophet (pbuh) said,
"Wearing gold and silk has been made unlawful for the men of my community but permissible for its women.” [Reported by At-Tirmidhi]
On the authority of Huzaifa Ibn AI- Yaman (may Allah be pleased with him) who said, "The Messenger of Allah (pbuh) made it unlawful for us to drink or eat in the vessel of gold or silver, to wear or set on silk.” [Reported by AI-Bukhari]
Therefore, he who makes wearing silk by men permissible, he is a disbeliever. The Prophet (pbuh) made it lawful only for the one who suffers from a certain disease such as scabies and for the soldiers in time of fighting. As for wearing silk for only ornament by men, it is unanimously prohibited. Whether it is a hat or a turban. Likewise, if the most of the cloth is silk, it is also unlawful. Wearing gold by men is also unlawful, whether it is a ring or a sheathe of sword. It is unlawful to wear or make it. Once, the Prophet (pbuh) saw a man wearing a ring of gold, took it off from his hand and said, "It is an easier act for anyone of you to handle afire brand than to do such thing.” [Reported by Muslim]
Likewise, the embroidery of gold on embellished turban is also unlawful. As for boys wearing gold and silver, the scholars are in disagreement. Some of them consider it permissible and some others consider it unlawful for the generality of the following saying of the Prophet (pbuh), "These two (gold and silk) are unlawful for men of my Ummah, but lawful for its women.” [Reported by Abu Dawud]
Thus, boys are included in this prohibition. This is also the opinion of Imam Ahmad and other (may Allah be pleased with them)
