Short answer
Yes. Pure silk clothing is haram for men in all four schools, while women may wear it. A silk border or trim up to four fingers wide is allowed, and in the Hanafi school cloth with a silk warp and a cotton weft is allowed. Satin or "silk feel" fabrics made of polyester are not silk.
Wearing silk is haram for men, except a strip or border up to four fingers wide. Cloth whose weft (the threads woven across) is not silk is permitted even if its warp is silk. Abu Hanifa did not allow silk clothing for men even for an itch or skin condition.
Other madhhabs
- Shafi'i
- Silk is allowed for a man who needs it for itching, lice or a skin condition, and in battle.
- Hanbali
- Silk is also allowed for a man who needs it for itching, lice or illness, and in battle when there is a need.
Explanation
The Prophet ﷺ said: do not wear silk, for whoever wears it in this world will not wear it in the Hereafter. Umar later told the Muslims that the only exception was a strip of two, three or four fingers. The same hadiths that forbid gold to men say silk is lawful for women.
Why silk? Scholars point to humility and avoiding luxury and softness that belong to women's adornment. But the real reason a Muslim avoids it is that the Prophet forbade it, and he knew best. The reward is promised in the hadith itself: silk is the clothing of the people of Paradise.
What counts. The ruling is about real silk from the silkworm. Polyester satin, viscose, rayon (often called "art silk") and other man-made fabrics are not silk. Mixed fabrics follow the Hanafi rule of the weft: if the threads running across are cotton, wool or synthetic, it is allowed. A pure silk tie, kurta or shirt for a man is not allowed, and neither is dressing boys in silk.
Small amounts. A silk lining patch, a trim on a jubba, or embroidery up to four fingers wide is fine. A tie is usually much wider than that when it is laid flat, so a silk tie is not covered by this exception.
