Musnad Abu Ya'la al-Mawsili 154:14

Zuhayr narrated to us, Ibn ‘Uyaynah narrated to us, from Zayd ibn Aslam, who said: I entered upon Ibn ‘Umar. My father had sent me to him, and he said: I heard the Messenger of Allah (may Allah bless him and grant him peace) say: "Allah will not look at the one who drags his lower garment out of pride."
