Muwatta Malik #1794

Yahya related to me from Malik from Nafi from Abdullah ibn Umar that Umar ibn al-Khattab saw a silk robe at the door of the mosque. He said, "Messenger of Allah, would you buy this robe and wear it on jumua and when envoys come to you?" The Messenger of Allah, may Allah bless him and grant him peace, said, "Only a person who has no portion in the next world wears this." Then the Messenger of Allah, may Allah bless him and grant him peace, was brought some robes of the same material and gave Umar ibn al-Khattab one of the robes. Umar said, "Messenger of Allah, do you clothe me in it when you said what you said about the robe of Utarid?" The Messenger of Allah, may Allah bless him and grant him peace, said, "I did not give it to you to wear." Umar gave it to a brother of his in Makka who was still an idolater.
