Musnad Ahmad 27:1982

Abdullah ibn al-Harith narrated to us, from Hanzalah ibn Abi Sufyan, from Salim ibn Abdullah, from Abdullah ibn Umar, that the Messenger of Allah (may Allah bless him and grant him peace) said: "Whoever drags his garment out of pride, Allah, Blessed and Exalted is He, will not look at him on the Day of Resurrection."
