Volume 7, Book 72, Number 732:
Narrated Abdullah bin Umar:
‘Umar saw a silk suit being sold, so he said, “O Allah’s Apostle! Why don’t you buy it so that you
may wear it when delegates come to you, and also on Fridays?” The Prophet said, “This is worn only
by him who has no share in the Hereafter.” Afterwards the Prophet sent to ‘Umar a silk suit suitable
for wearing. ‘Umar said to the Prophet, “You have given it to me to wear, yet I have heard you saying
about it what you said?” The Prophet said, “I sent it to you so that you might either sell it or give it to
somebody else to wear.”
