Musnad Ahmad 27:1086

Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, from Jabalah ibn Suhaym, who said: I heard Ibn 'Umar narrating from the Prophet, may Allah bless him and grant him peace, that he said: "Whoever drags a garment of his clothes out of pride, Allah will not look at him on the Day of Resurrection."
