The Messenger of Allah ﷺ said to me, "Recite the Quran in a month."I said, "I am able to do more than that."I kept pressing him until he said, "Recite the Quran in five days, and fast three days each month."I said, "I am able to do more than that."He replied, "Then fast the most beloved fast to Allah , the fast of Dawud
. He used to fast one day and break his fast the next."
