Muhammad ibn Yaqub, from Muhammad ibn Ismail, from al-Fadl ibn Shadhan, from Safwan ibn Yahya, from Is ibn al-Qasim, who said: I (narrator) asked Abu Abdillah عليه السلام, peace be upon him, about ‘a man who went out in the month of Ramadan while his companions were eating the pre-dawn meal in a house. He looked toward the dawn and called out to them, so some of them stopped, while some of them thought that he was mocking, so he ate.’ Imam عليه السلام said: “He completes his fast and makes it up.”
