English translation
1979. Narrated 'Abdullāh bin 'Amr bin Al-'Ās رضي الله عنهما: The Prophet ﷺ said to me, "You observe Saum (fast) daily all the year and offer Salāt (prayer) (every night) all the night?" I replied in the affirmative. The Prophet ﷺ said, "If you keep on doing this, your eyes will become weak and your body will get tired. He who observes Saum (fast) all the year is as he who did not observe Saum (fast) at all. Observing Saum (fast) of three days (a month) will be equal to observing Saum (fast) of the whole year." I replied, "I have the strength for more than this." The Prophet ﷺ said, "Then observe Saum (fast) like the fasting of Dāwūd (David) عليه السلام who used to observe Saum (fast) on alternate days and would never flee from the battle field on meeting the enemy."
