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  

[Machine] "To me, the Messenger of Allahﷺ said, 'O Abdullah bin Amr, it has reached me that you fast during the day and spend the night in prayer. Do not do so, for your body has rights over you, your wife has rights over you, and your eyes have rights over you. Fast and break your fast from every month for three days; that is the fast of a lifetime.' I said, 'O Messenger of Allah, I have the ability to do more.' He said, 'Fast the fast of Dawood: fast one day and break your fast the following day.' Abdullah used to say, 'I wish I had taken the concession.'"  

لِي رَسُولُ اللهِ ﷺ يَا عَبْدَ اللهِ بْنَ عَمْرٍو بَلَغَنِي أَنَّكَ تَصُومُ النَّهَارَ وَتَقُومُ اللَّيْلَ فَلَا تَفْعَلَنَّ فَإِنَّ لِجَسَدِكَ عَلَيْكَ حَظًّا وَإِنَّ لِزَوْجِكَ عَلَيْكَ حَظًّا وَإِنَّ لِعَيْنَيْكَ عَلَيْكَ حَظًّا أَفْطِرْ وَصُمْ مِنْ كُلِّ شَهْرٍ ثَلَاثَةَ أَيَّامٍ فَذَلِكَ صَوْمُ الدَّهْرِ قَالَ قُلْتُ يَا رَسُولَ اللهِ إِنِّي أَجِدُ قُوَّةً؟ قَالَ صُمْ صَوْمَ دَاوُدَ صُمْ يَوْمًا وَأَفْطِرْ يَوْمًا قَالَ فَكَانَ عَبْدُ اللهِ يَقُولُ يَا لَيْتَنِي كُنْتُ أَخَذْتُ بِالرُّخْصَةِ  

[Machine] The Messenger of Allah ﷺ said, "O Abdullah ibn Amr, I have been informed that you fast during the day and pray during the night. Do not do so. Your body has rights over you, and your soul has rights over you. Fast and break your fast, and fast for three days every month as a perpetual fast." Abdullah replied, "O Messenger of Allah, I find myself strong enough to do so." The Prophet said, "Observe the fast of Prophet David, fast one day and break your fast the next day." Abdullah ibn Amr used to say, "I wish that I had taken the concession."
