Musnad Abu Ya'la al-Mawsili 115:49

Hadaba narrated to us, Hammam narrated to us, from Qatada, who said: We used to come to Anas while his baker was standing. He said: "Eat, for I do not know that the Messenger of Allah (may Allah bless him and grant him peace) ever saw a thin loaf of bread, nor a roasted sheep with his own eyes, until he joined Allah, the Mighty and Majestic."
