Narrated `Abdullah bin `Amr bin Al-`As: Allah's Apostle said to me, "O `Abdullah! Have I not been informed that you fast during the day and offer prayers all the night." `Abdullah replied, "Yes, O Allah's Apostle!" The Prophet said, "Don't do that; fast for few days and then give it up for few days, offer prayers and also sleep at night, as your body has a right on you, and your wife has a right on you, and your guest has a right on you. And it is sufficient for you to fast three days in a month, as the reward of a good deed is multiplied ten times, so it will be like fasting throughout the year." I insisted (on fasting) and so I was given a hard instruction. I said, "O Allah's Apostle! I have power." The Prophet said, "Fast like the fasting of the Prophet David and do not fast more than that." I said, "How was the fasting of the Prophet of Allah, David?" He said, "Half of the year," (i.e. he used to fast on every alternate day). Afterwards when `Abdullah became old, he used to say, "It would have been better for me if I had accepted the permission of the Prophet (which he gave me i.e. to fast only three days a month).

Narrated `Abdullah bin `Amr: Allah's Apostle was informed that I had taken an oath to fast daily and to pray (every night) all the night throughout my life (so Allah's Apostle came to me and asked whether it was correct): I replied, "Let my parents be sacrificed for you! I said so." The Prophet said, "You can not do that. So, fast for few days and give it up for few days, r ray and sleep. Fast three days a month as the reward of good deeds is multiplied ten times and that will be equal to one year of fasting." I replied, "I can do better than that." The Prophet said to me, "Fast one day and give up fasting for a day and that is the fasting of Prophet David and that is the best fasting." I said, "I have the power to fast better (more) than that." The Prophet said, "There is no better fasting than that."

Abu Juhaifah Wahb bin Abdullah (may Allah be pleased with him) narrated this from the Prophet (peace and blessings of Allah be upon him).

Narrated `Abdullah bin `Amr: The news of my daily fasting and praying every night throughout the night reached the Prophet. So he sent for me or I met him, and he said, "I have been informed that you fast everyday and pray every night (all the night). Fast (for some days) and give up fasting (for some days); pray and sleep, for your eyes have a right on you, and your body and your family (i.e. wife) have a right on you." I replied, "I have more power than that (fasting)." The Prophet said, "Then fast like the fasts of (the Prophet) David". I said, "How?" He replied, "He used to fast on alternate days, and he used not to flee on meeting the enemy." I said, "From where can I get that chance?" (`Ata' said, "I do not know how the expression of fasting daily throughout the life occurred.") So, the Prophet said, twice, "Whoever fasts daily throughout his life is just as the one who does not fast at all."

Narrated Mujahid from `Abdullah bin `Amr: The Prophet said (to `Abdullah), "Fast three days a month." `Abdullah said, (to the Prophet) "I am able to fast more than that." They kept on arguing on this matter till the Prophet said, "Fast on alternate days, and recite the whole Qur'an once a month." `Abdullah said, "I can recite more (in a month)," and the argument went on till the Prophet said, "Recite the Qur'an once each three days." (i.e. you must not recite the whole Qur'an in less than three days).

Narrated `Abdullah bin `Amr bin Al-`As: The Prophet said to me, "You fast daily all the year and pray every night all the night?" I replied in the affirmative. The Prophet said, "If you keep on doing this, your eyes will become weak and your body will get tired. He who fasts all the year is as he who did not fast at all. The fasting of three days (a month) will be equal to the tasting of the whole year." I replied, "I have the power for more than this." The Prophet said, "Then fast like the fasting of David who used to fast on alternate days and would never flee from the battle field, on meeting the enemy.

Narrated `Abdullah bin `Amr: Allah's Apostle was informed about my fasts, and he came to me and I spread for him a leather cushion stuffed with palm fires, but he sat on the ground and the cushion remained between me and him, and then he said, "Isn't it sufficient for you to fast three days a month?" I replied, "O Allah's Apostle! (I can fast more)." He said, "Five?" I replied, "O Allah's Apostle! (I can fast more)." He said, "Seven?" I replied, "O Allah's Apostle! (I can fast more)." He said, "Nine (days per month)?" I replied, "O Allah's Apostle! (I can fast more)" He said, "Eleven (days per month)?" And then the Prophet said, "There is no fast superior to that of the Prophet David it was for half of the year. So, fast on alternate days."

Narrated Abu Huraira: My friend (the Prophet) advised me to observe three things: (1) to fast three days a month; (2) to pray two rak`at of Duha prayer (forenoon prayer); and (3) to pray witr before sleeping.

Narrated Anas: The Prophet paid a visit to Um-Sulaim and she placed before him dates and ghee. The Prophet said, "Replace the ghee and dates in their respective containers for I am fasting." Then he stood somewhere in her house and offered an optional prayer and then he invoked good on Um-Sulaim and her family. Then Um-Sulaim said, "O Allah's Apostle! I have a special request (today)." He said, "What is it?" She replied, "(Please invoke for) your servant Anas." So Allah's Apostle did not leave anything good in the world or the Hereafter which he did not invoke (Allah to bestow) on me and said, "O Allah! Give him (i.e. Anas) property and children and bless him." Thus I am one of the richest among the Ansar and my daughter Umaina told me that when Al-Hajjaj came to Basra, more than 120 of my offspring had been buried.

Narrated Mutarrif from `Imran Ibn Husain: That the Prophet asked him (Imran) or asked a man and `Imran was listening, "O Abu so-and-so! Have you fasted the last days of this month?" (The narrator thought that he said, "the month of Ramadan"). The man replied, "No, O Allah's Apostle!" The Prophet said to him, "When you finish your fasting (of Ramadan) fast two days (in Shawwal)." Through another series of narrators `Imran said, "The Prophet said, '(Have you fasted) the last days of Sha'ban?"
