The Prohibition of Wearing Silk for Men and its Permissibility for Women
وَعَنْ أَنَسٍ رضى اللَّهُ عَنْهُ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: مَنْ لَبِسَ الْحَرِيرَ فِي الدُّنْيَا لَمْ يَلْبَسْهُ فِي الآخِرَةِ .((مُتَّفَقٌ عَلَيْهِ))
Anas (May Allah be pleased with him) reported: The Messenger of Allah (ﷺ) said, "He who wears silk clothes in this life shall not wear them in the Hereafter." [Al-Bukhari and Muslim].
