Al-Adab Al-Mufrad #351

'Abdullah ibn 'Umar said, "'Umar found a silk robe and brought it to the Prophet, may Allah bless him and grant him peace, and said, 'Buy this and wear it on Jumu'ah and when delegations come to you.' The Prophet, peace be upon him, replied, 'Only someone 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 and sent one robe to 'Umar, one to Usama, and one to 'Ali. 'Umar said, 'Messenger of Allah! You have sent this to me when I heard you say what you said about it.' The Prophet, may Allah bless him and grant him peace, said, 'You can sell it or take care of your needs with it.'"
