" يَا عَبْدَ الله: أَلَمْ أُخْبرْ أَنَّكَ تَصُومُ النَّهَارَ، وَتَقُومُ اللَّيْلَ؟ فَلاَ تَفْعَلْ؛ فَإِنَّكَ إِذْ فَعَلْتَ هَجَمَتْ عَيْنُكَ، وَنَفِهَتْ نَفْسُكَ، فَصُمْ وَأَفْطِرْ، وَقُمْ وَنَمْ، فَإِنَّ لِجَسَدِكَ عَلَيْكَ حَقّا، وَلِعَيْنِكَ عَلَيْكَ حَقّا، وَإِنَّ لِزَوْجِكَ عَلَيْكَ حَقّا، وَإنَّ لِزوركَ عَليكَ حَقّا، وَإِنَّ بِحَسْبِكَ أَنْ تَصُومَ مِنْ كُلِّ شَهْرٍ ثَلاَثَةَ أَيَّامٍ، فَإِنَّ لَكَ بِكُلِّ حَسَنَةٍ عَشْرَةَ أَمْثَالِهَا، فَإِنَّ ذَلِكَ صيَامُ الدَّهْرِ كُلِّهِ، قَالَ: إِنِّى أَجِدُ قُوَّةً، قَالَ: فَصُمْ صِيَامَ نَبِىِّ الله دَاوُدَ وَلاَ تَزِدْ عَلَيْهِ (نصفُ الدَّهْر) ".
See similar narrations below:
Collected by Bukhārī, Muslim, Nasāʾī, Aḥmad, Ibn Ḥibbān, Nasāʾī's KubráMessenger of Allah ﷺ said to me, "O ʿAbdullah! Have I not been informed that you fast during the day and offer prayers all the night." ʿAbdullah replied, "Yes, O Messenger of Allah ﷺ!" The Prophet ﷺ 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 Messenger of Allah ﷺ! I have power." The Prophet ﷺ said, "Fast like the fasting of the Prophet ﷺ David and do not fast more than that." I said, "How was the fasting of the Prophet ﷺ of Allah, David?" He said, "Half of the year," (i.e. he used to fast on every alternate day). Afterwards when ʿAbdullah 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).

Messenger of Allah ﷺ 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 ﷺ said, "Fast as Allah's prophet David used to fast." I said, "How was the fasting of the prophet David?" The Prophet ﷺ said, "One half of a year (i.e. he used to fast on alternate days). '
دَخَلَ عَلَىَّ رَسُولُ اللَّهِ ﷺ فَقَالَ أَلَمْ أُخْبَرْ أَنَّكَ تَقُومُ اللَّيْلَ وَتَصُومُ النَّهَارَ قُلْتُ بَلَى قَالَ فَلاَ تَفْعَلْ قُمْ وَنَمْ وَصُمْ وَأَفْطِرْ فَإِنَّ لِجَسَدِكَ عَلَيْكَ حَقًّا وَإِنَّ لِعَيْنِكَ عَلَيْكَ حَقًّا وَإِنَّ لِزَوْرِكَ عَلَيْكَ حَقًّا وَإِنَّ لِزَوْجِكَ عَلَيْكَ حَقًّا وَإِنَّكَ عَسَى أَنْ يَطُولَ بِكَ عُمُرٌ وَإِنَّ مِنْ حَسْبِكَ أَنْ تَصُومَ مِنْ كُلِّ شَهْرٍ ثَلاَثَةَ أَيَّامٍ فَإِنَّ بِكُلِّ حَسَنَةٍ عَشْرَ أَمْثَالِهَا فَذَلِكَ الدَّهْرُ كُلُّهُ قَالَ فَشَدَّدْتُ فَشُدِّدَ عَلَىَّ فَقُلْتُ فَإِنِّي أُطِيقُ غَيْرَ ذَلِكَ قَالَ فَصُمْ مِنْ كُلِّ جُمُعَةٍ ثَلاَثَةَ أَيَّامٍ قَالَ فَشَدَّدْتُ فَشُدِّدَ عَلَىَّ قُلْتُ أُطِيقُ غَيْرَ ذَلِكَ قَالَ فَصُمْ صَوْمَ نَبِيِّ اللَّهِ دَاوُدَ قُلْتُ وَمَا صَوْمُ نَبِيِّ اللَّهِ دَاوُدَ قَالَ نِصْفُ الدَّهْرِ
Then observe the fast of David (peace be upon him). Observe fast one day and break it (on the other) day. And he ('Abdullah b. 'Amr) used to say: Would that I had availed myself of this concession.
لِي رَسُولُ اللَّهِ ﷺ يَا عَبْدَ اللَّهِ بْنَ عَمْرٍو بَلَغَنِي أَنَّكَ تَصُومُ النَّهَارَ وَتَقُومُ اللَّيْلَ فَلاَ تَفْعَلْ فَإِنَّ لِجَسَدِكَ عَلَيْكَ حَظًّا وَلِعَيْنِكَ عَلَيْكَ حَظًّا وَإِنَّ لِزَوْجِكَ عَلَيْكَ حَظًّا صُمْ وَأَفْطِرْ صُمْ مِنْ كُلِّ شَهْرٍ ثَلاَثَةَ أَيَّامٍ فَذَلِكَ صَوْمُ الدَّهْرِ قُلْتُ يَا رَسُولَ اللَّهِ إِنَّ بِي قُوَّةً قَالَ فَصُمْ صَوْمَ دَاوُدَ عَلَيْهِ السَّلاَمُ صُمْ يَوْمًا وَأَفْطِرْ يَوْمًا فَكَانَ يَقُولُ يَا لَيْتَنِي أَخَذْتُ بِالرُّخْصَةِ
"The Messenger of Allah entered my apartment and said: "I have been told that you stand all night (in prayer) and fast all day.' I said: 'Yes (I do).' He said: 'Do not do that.

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 ableto do more thtn that; I was strict, so I was dealt with strictly. He said: 'Observe the fast of the Prophet of Allah, Dawud, peace be upon him.

[Machine] I, the Messenger of Allah ﷺ , have informed that you stand the night and fast during the day. He said, I said, "O Messenger of Allah, yes."

I said, "O Messenger of Allah, I find strength." He said, "Fast the fast of the Prophet Davidﷺ and do not exceed it." I said, "O Messenger of Allah, what was the fast of David?"
