'Umar went out and saw a Hullah of Al-Istabraq being offered for sale in the marketplace. He went to the Messenger of Allah and he gave one to 'Umar, one to 'Ali and one to Usamah. He ('Umar) came to him and said: "O Messenger of Allah, you said what you said about it, then you sent one to me!" He said: "Sell it and spend the money on your needs, or cut it into pieces for your womenfolk to use as head covers."
Sunan an-Nasa'i Book 48, Hadith 260
