I went with your father to visit Abdullah bin Amr, and he told us that the Messenger of Allah ﷺ had been informed about his fasting. The Prophet ﷺ came to visit him, and he placed for him a leather cushion stuffed with palm fibers. The Prophet ﷺ sat on the ground, and the cushion remained between them.The Prophet ﷺ said to him, "Is it not enough for you to fast three days of every month?"He replied, "Messenger of Allah, more than that."The Prophet ﷺ said, "Then five."He replied, "Messenger of Allah, more than that."The Prophet ﷺ said, "Then seven."He replied, "Messenger of Allah, more than that."The Prophet ﷺ said, "Then nine."He replied, "Messenger of Allah, more than that."The Prophet ﷺ said, "Then eleven."He replied, "Messenger of Allah, more than that."The Prophet ﷺ then said, "There is no fasting beyond the fasting of Dawud, half of all time, fasting one day and breaking fast the next."
