I read about the fiqh of Ramadan on one website and it says if one violates the fast while eating he must fast for two consecutive months as kafarrah. It said one sahabi ate in the day in Ramadan and the Prophet (sallallahu’alaihi wasallam) ordered him to expiate it by fasting as mentioned above. It said it was in Sunan Daraqutni. Is there a hadith saying this? as i’m unsure of its authenticity.
