Whenever the Prophet ﷺ broke his fast at someone's home, he would say, "May those who fast break their fast at your table, may the righteous eat your food, and may the angels descend upon you."
حدثنا وكيع حدثنا هشام وإسحاق الأزرق قال أخبرنا الدستوائي عن يحيى بن أبي كثير
كان النبي ﷺ إذا أفطر عند أهل بيت قال أفطر عندكم الصائمون وأكل طعامكم الأبرار وتنزلت عليكم الملائكة
Its isnad is sahih. Hisham is Dastawai, and Dastawai is Hisham. The hadith was reported by Abu Dawud, 3/367, no. 3854, in the Book of Foods, chapter on what has been said about supplicating for the one who provides food, and Ibn Majah, 1/556, no. 1747.
