Musannaf Ibn Abi Shayba 13:2393

Abu Bakr narrated to us, he said: Ibn ‘Ulayyah narrated to us, from Ayyub and Ibn ‘Awn, from Muhammad, that a man dyed a garment of his the color of Harawi [cloth]. A man came and said, "For how much will you sell the Harawi [garment]?" He remained silent, then he bargained with him, and he bought it from him. When he took it away, it turned out not to be Harawi. So he disputed with him before Shurayh. He [Shurayh] said, "If he were able to adorn his garment with something better than that, he would have adorned it," and he upheld the sale for him.
