Al-Adab Al-Mufrad #26

Ibn 'Umar said, "'Umar saw a silk robe for sale. He said, 'Messenger of Allah, would you buy this robe and wear it on Jumu'a and when delegations visit you?' He replied, 'Only a person who has no portion in the Next World could wear this.' Then the Messenger of Allah, may Allah bless him and grant him peace, was given some robes made of the same material. He sent one of the robes to 'Umar. 'Umar exclaimed, 'How can I wear it when you said what you said about it?' The Prophet replied, 'I did not give it to you so that you could wear it. You can sell it or give it to someone.' 'Umar sent it to a brother of his in Makka who had not yet become Muslim."
