2405. ‘Abdullâh bin ‘Amr said: “The Messenger of Allâh ﷺ said to me: ‘Fast one day of the month and you will have the reward of what is left.’ I said: ‘I am able to do more than that.’ He said: ‘Fast two days and you will have the reward of what is left.’ I said: ‘I am able to do more than that.’ He said: ‘Fast three days and you will have the reward of what is left.’ I said: ‘I am able to do more than that.’ He said: ‘Fast four days and you will have the reward of what is left.’ I said: ‘I am able to do more than that.’ The Messenger of Allâh ﷺ said: ‘The best fasting is the fast of Dâwûd; he used to fast one day and not the next.’” (Sahîh)
