Musannaf Ibn Abi Shayba 16:610

Abu Bakr narrated to us, he said: Husayn bin Ali narrated to us, from Ibn Abi Rawwad, from Salim, from his father, from the Prophet (peace and blessings of Allah be upon him), who said: "Letting the garment hang down (is) in the lower garment (izar), the shirt (qamis), and the turban (imama). Whoever drags any part of them out of pride, Allah will not look at him on the Day of Resurrection."
