Musannaf Ibn Abi Shayba 27:489

Khalaf ibn Khalifah narrated to us, from Abu Harun, who said: I was sitting with Ibn Umar when Nafi’ ibn al-Azraq came to him and stood over his head. He said, "By Allah, I truly hate Ali." Ibn Umar raised his head toward him and said, "May Allah hate you. You hate a man whose one merit is better than the world and what is in it."
