The Prohibition of Wearing Silk for Men and its Permissibility for Women
وَعَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: "إِنَّمَا يَلْبَسُ الْحَرِيرَ مَنْ لاَ خَلاَقَ لَهُ".((مُتَّفَقٌ عَلَيْهِ)) وفى رِوَايَةٍ لِلْبُخَارِيِّ: "مَنْ لاَ خَلاَقَ لَهُ فِي الآخِرَةِ"
'Umar bin Al-Khattab (May Allah be pleased with him) reported: I heard the Messenger of Allah (ﷺ) saying, "Silk (clothes) are worn only by he who has no share in the Hereafter." [Al-Bukhari and Muslim]. Another narration is: "Who has no share in the Hereafter."
