Sahih al-Bukhari 2612
صحيح البخاري#2612SahihNarrated `Abdullah bin `Umar:`Umar bin Al-Khattab saw a silken dress (cloak) being sold at the gate of the Mosque and said, "O Allah's Messenger (ﷺ)! Would that you buy it and wear it on Fridays and when the delegates come to you!" Allah's Messenger (ﷺ) said, "This is worn by the one who will have no share in the Hereafter." Later on some silk dresses were brought and Allah's Messenger (ﷺ) sent one of them to `Umar. `Umar said, "How do you give me this to wear while you said what you said about the dress of 'Utarid?" Allah's Messenger (ﷺ) said, "I have not given it to you to wear." So, `Umar gave it to a pagan brother of his in Mecca
