From Sahih Muslim (Hadith 6351):
Anas b Malik reported that Allah's Messenger (ﷺ) was presented a garment of sundus and he prohibited the use of silk. The persons admired it, whereupon he said:By Him in Whose Hand is the life of Muhammad, the kerchiefs of Sa'd b. Mu'adh in Paradise are better than this
