Musnad Abu Ya'la al-Mawsili 117:47

Hadbata narrated to us, Hammad narrated to us, from Thabit, from Anas, from the Prophet (peace be upon him), who said: "When Allah created Adam, Iblis began to circle around him, looking at him. When he saw that he was hollow, he said: 'I have succeeded; [this is] a creation that does not control itself.'"
