I heard Abdullah bin Zubayr, while delivering a sermon from the pulpit, say, "Muhammad ﷺ said, 'Whoever wears silk in this world will not wear it in the Hereafter.'"
أخبرنا قتيبة قال حدثنا حماد
سمعت عبد الله بن الزبير وهو على المنبر يخطب ويقول قال محمد ﷺ من لبس الحرير في الدنيا فلن يلبسه في الآخرة
Bukhari reported it in the Book of Clothing, Chapter on wearing silk for men and how much of it is permissible, hadith no. 5833, from the hadith of Hammad bin Zayd with the same chain.
