The Prophet (ﷺ) said, Whoever wears silk in this world shall not wear it in the Hereafter."
Sahih al-Bukhari Book 77, Hadith 49
← Previous Hadith While Hudhaifa was at Al-Madain, he asked for water whereupon the chief of the village brought him water in a silver cup. Hudhaifa threw it at him and said, "I have thrown it only because I have forbidden him to use it, but he does not stop using it. Allah's Messenger (ﷺ) said, 'Gold, silver, silk and Dibaj (a kind of silk) are for them (unbelievers) in this world and for you (Muslims) in the hereafter.'

Sahih al-Bukhari Book 77, Hadith 48 Next Hadith → I heard Ibn Az-Zubair delivering a sermon, saying, "Muhammad said, 'Whoever wears silk in this world, shall not wear it in the Hereafter."
