The Prohibition of Wearing Silk for Men and its Permissibility for Women
عَنْ عُمَرَ بْنِ الْخَطَّابِ رضى اللَّه عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ : لاَ تلبسوا الحرير؛ فإن مَنْ لَبِسَهُ فِي الدُّنْيَا لَمْ يَلْبَسْهُ فِي الآخِرَةِ .((مُتَّفَقٌ عَلَيْهِ))
`Umar bin Al-Khattab (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) said, "Do not wear silk (clothes). For whoever wears (them) in this life will be deprived of them in the Hereafter." [Al-Bukhari and Muslim].
