Sayyiduna Anas bin Malik (may Allah be pleased with him) said that when the Messenger of Allah (peace and blessings be upon him) broke his fast with a people, he would say to them: 'Aftara 'indakumu al-sa'imun, wa akala ta'amakumu al-abrar, wa tanazzalat 'alaykumu al-mala'ikah' ("May fasting people break their fast with you, may the righteous eat your food, and may the angels descend upon you.")
This is mursal: Yahya did not hear it from Anas; he only heard it from a man of Basrah called Amr bin Zunayb, or Ibn Zabib, from Anas.

Sayyiduna Anas (may Allah be pleased with him) said that the Messenger of Allah (peace and blessings be upon him) sought permission to enter upon Sayyiduna Sa'd bin Ubadah (may Allah be pleased with him), and he narrated the hadith: then he (peace and blessings be upon him) entered the house. He brought raisins near him (peace and blessings be upon him), and the Messenger of Allah (peace and blessings be upon him) ate; when he had finished, he (peace and blessings be upon him) said: 'Akala ta'amakumu al-abrar, wa sallat 'alaykumu al-mala'ikah, wa aftara 'indakumu al-sa'imun' ("The righteous have eaten your food, the angels have prayed for mercy upon you, and fasting people have broken their fast with you.")
