Chapter 90: Stern Warning Against Wearing Silk, and That Whoever Wears it in This World Will Not Wear it in the Hereafter - كتاب الزينة من السنن
أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا حَمَّادٌ، عَنْ ثَابِتٍ، قَالَ سَمِعْتُ عَبْدَ اللَّهِ بْنَ الزُّبَيْرِ، وَهُوَ عَلَى الْمِنْبَرِ يَخْطُبُ وَيَقُولُ قَالَ مُحَمَّدٌ صلى الله عليه وسلم " مَنْ لَبِسَ الْحَرِيرَ فِي الدُّنْيَا فَلَنْ يَلْبَسَهُ فِي الآخِرَةِ " .
'Abdullah bin Az-Zubair said, while he was on the Minbar delivering a Khutbah:
"Muhammad [SAW] said: 'Whoever wears silk in this world, will not wear it in the Hereafter.'"
