Musnad Ahmad 1155:47

'Abd al-Rahman ibn Mahdi, Abu Kamil, and 'Affan narrated to us, they said: Hammad ibn Salamah narrated to us, 'Affan said in his narration: He informed us, Anas ibn Sirin, from Abu Mijlaz, from Hafsah, that 'Utarid ibn Hajib arrived with a garment of brocade that Chosroes had clothed him with. 'Umar said: "O Messenger of Allah, if only you would buy it." He said: "Indeed, only he who has no share [in the Hereafter] wears it."
