It was narrated that 'Abdullah bin Shaqiq said: "I said to Aishah: “Did the Messenger of Allah offer Duha prayer? She said: "No, unless he was returning from a journey, I Did the Messenger of Allah fast an entire month?' She said: “No, I do not remember him fasting any month in full apart from Ramadan, and he did not break his fast for a whole month, rather he would fast some of (each month) until he passed away””
