From Sahih Muslim (Hadith 5424):
Anas b. Malik reported that Allah's Messenger (may Peace be upon him) sent a silk gown to 'Umar, whereupon 'Umar said:You sent it to me whereas you said what you had to, say (i. e. it is forbidden for men). Thereupon he (the Holy Prophet) said: I did not send it to you so that you might wear it, but I sent it to you so that you might derive benefit from its price
