قَوْلُهُ تَعَالَى: {وَلِبَاسُهُمْ فِيهَا حَرِيرٌ} [الحج: 23]
I heard Ibn Az-Zubair delivering a sermon, saying, "Muhammad said, 'Whoever wears silk in this world, shall not wear it in the Hereafter." (Using translation from Bukhārī 5833)
مُحَمَّدٌ ﷺ «مَنْ لَبِسَ الْحَرِيرَ فِي الدُّنْيَا لَمْ يَلْبَسْهُ فِي الْآخِرَةِ»
