Narrated `Abdullah bin `Amr bin Al-`As: Allah's Apostle told me, "The most beloved prayer to Allah is that of David and the most beloved fasts to Allah are those of David. He used to sleep for half of the night and then pray for one third of the night and again sleep for its sixth part and used to fast on alternate days."

Narrated `Abdullah bin `Amr bin Al-`As: Allah's Apostle said to me, "O `Abdullah! Do not be like so and so who used to pray at night and then stopped the night prayer."

Narrated 'Abdullah bin 'Amr: Once Allah's Messenger (saws) said to me, "I have been informed that you offer Salat (prayer) all the night and observe Saum (fast) during the day." I said, "(Yes) I do so." He said, "If you do so, your eye sight will become weak and you will become weak. No doubt, your body has right on you, and your family has right on you, so observe Saum (for some days) and do not observe it (for some days), offer Salat (for sometime) and then sleep."

Narrated `Abdullah bin `Amr bin Al-`As: "Once Allah's Apostle came to me," and then he narrated the whole narration, i.e. your guest has a right on you, and your wife has a right on you. I then asked about the fasting of David. The Prophet replied, "Half of the year," (i.e. he used to fast on every alternate day).

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."

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 `Abdullah bin `Amr: Allah's Apostle was informed that I have said: "By Allah, I will fast all the days and pray all the nights as long as I live." On that, Allah's Apostle asked me. "Are you the one who says: 'I will fast all the days and pray all the nights as long as I live?' " I said, "Yes, I have said it." He said, "You cannot do that. So fast (sometimes) and do not fast (sometimes). Pray and sleep. Fast for three days a month, for the reward of a good deed is multiplied by ten time, and so the fasting of three days a month equals the fasting of a year." I said, "O Allah's Apostle! I can do (fast) more than this." He said, "Fast on every third day. I said: I can do (fast) more than that, He said: "Fast on alternate days and this was the fasting of David which is the most moderate sort of fasting." I said, "O Allah's Apostle! I can do (fast) more than that." He said, "There is nothing better than that."

Narrated `Abdullah bin `Amr bin Al-As: The Prophet said to me, "I have been informed that you pray all the nights and observe fast all the days; is this true?" I replied, "Yes." He said, "If you do so, your eyes will become weak and you will get bored. So fast three days a month, for this will be the fasting of a whole year, or equal to the fasting of a whole year." I said, "I find myself able to fast more." He said, "Then fast like the fasting of (the Prophet) David who used to fast on alternate days and would not flee on facing the enemy."

Narrated `Abdullah bin `Amr: Allah's Apostle said to me, "The most beloved fasting to Allah was the fasting of (the Prophet) David who used to fast on alternate days. And the most beloved prayer to Allah was the prayer of David who used to sleep for (the first) half of the night and pray for 1/3 of it and (again) sleep for a sixth of it."

Narrated `Abdullah bin `Amr bin Al `As: My father got me married to a lady of a noble family, and often used to ask my wife about me, and she used to reply, "What a wonderful man he is! He never comes to my bed, nor has he approached me since he married me." When this state continued for a long period, my father told the story to the Prophet who said to my father, "Let me meet him." Then I met him and he asked me, "How do you fast?" I replied, "I fast daily," He asked, "How long does it take you to finish the recitation of the whole Qur'an?" I replied, "I finish it every night." On that he said, "Fast for three days every month and recite the Qur'an (and finish it) in one month." I said, "But I have power to do more than that." He said, "Then fast for three days per week." I said, "i have the power to do more than that." He said, "Therefore, fast the most superior type of fasting, (that is, the fasting of (prophet) David who used to fast every alternate day; and finish the recitation of the whole Qur'an In seven days." I wish I had accepted the permission of Allah's Apostle as I have become a weak old man. It is said that `Abdullah used to recite one-seventh of the Qur'an during the day-time to some of his family members, for he used to check his memorization of what he would recite at night during the daytime so that it would be easier for him to read at night. And whenever he wanted to gain some strength, he used to give up fasting for some days and count those days to fast for a similar period, for he disliked to leave those things which he used to do during the lifetime of the Prophet.

Narrated `Abdullah bin `Amr: The Prophet asked me, "How long does it take you to finish the recitation of the whole Qur'an?"

Narrated `Abdullah bin `Amr: Allah's Apostle said to me, "Recite the whole Qur'an in one month's time." I said, "But I have power (to do more than that)." Allah's Apostle said, "Then finish the recitation of the Qur'an in seven days, and do not finish it in less than this period."

Narrated `Abdullah bin `Amr bin Al-`As: Allah's Apostle said, "O `Abdullah! Have I not been formed that you fast all the day and stand in prayer all night?" I said, "Yes, O Allah's Apostle!" He said, "Do not do that! Observe the fast sometimes and also leave them (the fast) at other times; stand up for the prayer at night and also sleep at night. Your body has a right over you, your eyes have a right over you and your wife has a right over you."

Narrated `Abdullah bin `Amr: Allah's Apostle entered upon me and said, "Have I not been informed that you offer prayer all the night and fast the whole day?" I said, "Yes." He said, "Do not do so; Offer prayer at night and also sleep; Fast for a few days and give up fasting for a few days because your body has a right on you, and your eye has a right on you, and your guest has a right on you, and your wife has a right on you. I hope that you will have a long life, and it is sufficient for you to fast for three days a month as the reward of a good deed, is multiplied ten times, that means, as if you fasted the whole year." I insisted (on fasting more) so I was given a hard instruction. I said, "I can do more than that (fasting)" The Prophet said, "Fast three days every week." But as I insisted (on fasting more) so I was burdened. I said, "I can fast more than that." The Prophet said, "Fast as Allah's prophet David used to fast." I said, "How was the fasting of the prophet David?" The Prophet said, "One half of a year (i.e. he used to fast on alternate days). '

Narrated `Abdullah bin `Amr: The news of my fasting was mentioned to the Prophet . So he entered upon me and I put for him a leather cushion stuffed with palm-fibres. The Prophet sat on the floor and the cushion was between me and him. He said to me, "Isn't it sufficient for you (that you fast) three days a month?" I said, "O Allah's Apostle! (I can fast more than this)." He said, "You may fast) five days a month." I said, "O Allah's Apostle! (I can fast more than this)." He said, "(You may fast) seven days." I said, "O Allah's Apostle!" He said, "Nine." I said, "O Allah's Apostle!" He said, "Eleven." I said, "O Allah's Apostle!" He said, "No fasting is superior to the fasting of (the Prophet David) which was one half of a year, and he used, to fast on alternate days. (See Hadith No. 300, Vol 3)
