Musnad Ahmad 27:739

Yahya narrated to us, from Sufyan, Abdullah ibn Dinar narrated to me, I heard Ibn Umar, from the Prophet (peace and blessings of Allah be upon him), who said: "The likeness of the one who drags his lower garment or his garment—Yahya was in doubt—out of pride, Allah will not look at him on the Day of Resurrection."
