The Messenger of Allah ﷺ said, "Whoever wears silk in this world will not wear it in the Hereafter."
حدثنا يحيى بن سعيد عن هشام أخبرنا قتادة عن داود السراج
قال رسول الله ﷺ من لبس الحرير في الدنيا لم يلبسه في الآخرة
Its isnad is sahih. Dawud Sarraj is the Egyptian, they did not mention him by the name of a father or grandfather, and he is acceptable. The hadith is found in Bukhari 7/193, in the Book of Clothing, chapter on wearing silk, and in Muslim, in the Book of Clothing 3/1645, number 2073, chapter on the prohibition of using vessels of gold.
