“The Prophet said, ‘Whoever fasts continually he neither fasts nor breaks his fast.’”[108]
“There is no fasting for one who fasts continually.”[109]
A man came to the Messenger of Allah [saws] and said, ‘O Messenger of Allah [saws] what do you say about a man who fasted for the rest of his life?’ The Messenger of Allah [saws] said, ‘I wish that he would never eat for the rest of his life.’ He said, ‘Two-thirds [of a lifetime]?’ He said, ‘That is too much.’ He said, ‘Half?’ He said, ‘That is too much.’ He said, ‘Shall I not tell you of that which will take away impurity from the heart?’ He said, ‘Yes.’ He said, ‘Fasting for three days each month.’”[110]
“A man came to the Prophet [saws] and said, ‘O Messenger of Allah! How do you fast?’ The Messenger of Allah [saws] got angry at what he said. When ‘Umar [ra] observed this he said, “We are satisfied with Allah [swt] as our Lord Islam as our religion and Muhammad [saws] as our Prophet. We seek refuge in Allah [swt] from the anger of Allah [swt] and the anger of His Messenger.’ Umar [ra] kept on repeating these words until the anger of the Prophet [saws] receded. He then said, ‘O Messenger of Allah [saws]! What about a person who fasts continuously?’ He said, ‘He is neither fasting nor breaking fast.’ He said, ‘O Messenger of Allah [saws]! What about a person who fasts two days and does not fast one day?’ He said, ‘Is there anybody who can do that?’ He said, ‘O Messenger of Allah [saws]! What about a person who fasts for a day and breaks his fast for a day?’ He said, ‘That is the fast of Dawud [as].’ He said, ‘O Messenger of Allah [saws]! What about a person who fasts for a day and breaks his fast for two days?’ He said, ‘I wish I could do that.’ Then the Messenger of Allah [saws] said, ‘[Fasting] three days from every month and Ramadan to Ramadan this is fasting all the time. And fasting the day of ‘Arafah; I hope from Allah [swt] that it may expiate for [the sins of] the preceding and the following year. And fasting the day of ‘Ashura’; I hope from Allah [swt] that it may atone for the sins of the preceding year.’”[111]
“The Messenger of Allah [saws] entered my apartment and said, ‘I have been told that you stand all night [in prayer] and fast all day.’ I [‘Abdullah bin ‘Amr bin Al-‘As (ra)] said, ‘Yes.’ He said, ‘Do not do that. Sleep and stand [in prayer]; fast and break your fast. For your eyes have a right over you, your body has a right over you, your wife has a right over you, your guest has a right over you and your friend has a right over you. I hope that you will have a long life and that it will be sufficient for you to fast three days of each month. That is fasting for a lifetime because a good deed is equal to ten like it.’ I said, ‘I feel able to do more.’ I was strict, so I was dealt with strictly. He said, ‘Fast three days each week.’ I said, ‘I am able to do more than that.’ I was strict, so I was dealt with strictly. He said, ‘Observe the fast of the Prophet of Allah [swt], Dawud peace be upon him.’ I said, ‘What was the fast of Dawud?’ He said, ‘Half of a lifetime.’”[112]
