Musnad Abu Ya'la al-Mawsili 117:242

Zuhayr narrated to us, Affan narrated to us, Hammad narrated to us, from Thabit, from Anas, that a man said: "O Messenger of Allah, where is my father?" He said: "In the Fire." When he turned to leave, he called him back and said: "Indeed, my father and your father are in the Fire."
