"I asked 'A'isha (may Allah the Exalted be well pleased with her) about the fasting of Allah’s Messenger (Allah bless him and give him peace). She said: “He used to fast until we would say: ‘He has fasted,’ and he used to break fast until we would say: ‘He has broken fast.’” She also said: “Allah’s Messenger (Allah bless him and give him peace) did not fast for a whole month after arriving in Medina, with the exception of Ramadan.’
