Musnad Abu Ya'la al-Mawsili 148:70

Uqbah ibn Mukram narrated to us, Yunus ibn Bukayr narrated to us, Hisham al-Dastawa'i narrated to us, from Yahya ibn Abi Kathir, from Anas ibn Malik, who said: When the Messenger of Allah (may Allah bless him and grant him peace) would break his fast with a household, he would say: "The fasting ones have broken their fast with you, the righteous have eaten your food, and the angels have descended upon you."
