It was conveyed to the Messenger of Allah ﷺ that I observe fast successively and pray during the whole night. He sent for me or I met him and he (the Holy Prophet) said: It has been conveyed to me that you observe fast continuously and do not break it and pray during the whole night. Don't do that. for there is share for your eyes, share for your own self, share for your family; so observe fast and break it, pray and sleep and observe fast for one day during the ten days, and there is a reward for you (for other) nine (days besides the tenth day of the fast). I said: Apostle of Allah, I find myself more powerful than this. He said: Then observe the fast of David (peace be upon him). He ('Amr) said: Apostle of Allah, how did David observe fast? He (the Holy Prophet) said: He used to fast one day and break it on the other day, and he did not run (from the battlefield) as he encountered (the enemy). He said: Apostle of Allah, who can guarantee this for me (will I also encounter the enemy dauntlessly)? 'Ata', the narrator of the hadith, said: I do not know how there (crept in) the matter of perpetual fast. The Apostle of Allah ﷺ, however, said: He who observed perpetual fast did not fast at all; he who observed perpetual fast did not fast at all, he who observed perpetual fast did not fast at all.  

أَخْبَرَهُ أَنَّهُ سَمِعَ عَبْدَ اللَّهِ بْنَ عَمْرِو بْنِ الْعَاصِ ؓ يَقُولُ بَلَغَ النَّبِيَّ ﷺ أَنِّي أَصُومُ أَسْرُدُ وَأُصَلِّي اللَّيْلَ فَإِمَّا أَرْسَلَ إِلَىَّ وَإِمَّا لَقِيتُهُ فَقَالَ أَلَمْ أُخْبَرْ أَنَّكَ تَصُومُ وَلاَ تُفْطِرُ وَتُصَلِّي اللَّيْلَ فَلاَ تَفْعَلْ فَإِنَّ لِعَيْنِكَ حَظًّا وَلِنَفْسِكَ حَظًّا وَلأَهْلِكَ حَظًّا فَصُمْ وَأَفْطِرْ وَصَلِّ وَنَمْ وَصُمْ مِنْ كُلِّ عَشْرَةِ أَيَّامٍ يَوْمًا وَلَكَ أَجْرُ تِسْعَةٍ قَالَ إِنِّي أَجِدُنِي أَقْوَى مِنْ ذَلِكَ يَا نَبِيَّ اللَّهِ قَالَ فَصُمْ صِيَامَ دَاوُدَ عَلَيْهِ السَّلاَمُ قَالَ وَكَيْفَ كَانَ دَاوُدُ يَصُومُ يَا نَبِيَّ اللَّهِ قَالَ كَانَ يَصُومُ يَوْمًا وَيُفْطِرُ يَوْمًا وَلاَ يَفِرُّ إِذَا لاَقَى قَالَ مَنْ لِي بِهَذِهِ يَا نَبِيَّ اللَّهِ قَالَ عَطَاءٌ فَلاَ أَدْرِي كَيْفَ ذَكَرَ صِيَامَ الأَبَدِ فَقَالَ النَّبِيُّ ﷺ لاَ صَامَ مَنْ صَامَ الأَبَدَ لاَ صَامَ مَنْ صَامَ الأَبَدَ لاَ صَامَ مَنْ صَامَ الأَبَدَ  

"The Messenger of Allah heard that I was fasting continually and praying all night." Either he sent for him, or he happened to meet him and he said: "Have I not been told that you fast and never break your fast, and you pray all night? Do not do that, for do that, for your eyes should have a share, your self should have a share, and your family should have a share. Fast and break your fast; pray and sleep. Fast one day out of every ten, and your will have the reward of the other nine." He said: " I am able to do more than that, O Messenger of Allah." He said: "Observe the fast of Dawud then." " I said: 'How did Dawud fast, O Prophet of Allah? He said: 'He used to fast one day, and not the next, and he never fled if he met(the enemy in battle)."' He said: "How can I compare to him, O Prophet of Allah?"
