Musnad Abu Ya'la al-Mawsili 155:59

'Amr ibn al-Dahhak narrated to us, my father narrated to us, Jurayj informed us, Nu'man informed me, from Ibn Shihab, that he informed him, from Sa'id ibn al-Musayyib, from Abu Hurayrah, from the Prophet (may Allah bless him and grant him peace), who said: "When one of you eats, let him eat with his right hand, and let him drink with his right hand, for indeed, Satan eats with his left hand and drinks with his left hand."
