Sahih Muslim | Book 24 | Hadith Number 5158
Narrated by Jabir b. Abdullah
Jabir b. Abdullah reported that one day Allah's Apostle (may peace be upon him) put on a cloak made of brocade, which had been presented to him. He then quickly put it off and sent it to 'Umar b. Khattab, and it was said to him: Messenger of Allah, why is it that you put it of immediately, whereupon he said: Gabriel forbade me from it (i.e. wearing of silk garment), and 'Umar came to him weeping and said: Messenger of Allah you disapproved a thing but you gave it to me. What about me, then? Thereupon be (the Holy Prophet) said: I did not give it to you to wear it, but I gave you that you might sell it; and so he (Hadrat Umar) sold it for two thousand dirhams.
