Musnad Abu Ya'la al-Mawsili 148:72

Ahmad ibn Isa al-Masri narrated to us, Ibn Wahb narrated to us, al-Khalil ibn Murrah informed me that Yahya ibn Abi Kathir al-Yamami narrated to him, from Anas ibn Malik, who said: When the Messenger of Allah (peace and blessings of Allah be upon him) 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."
