3419. Narrated 'Abdullāh bin 'Amr bin Al-Ās رَضِيَ اللَّهُ عَنْهُمَا: The Prophet ﷺ said to me, "I have been informed that you offer Ṣalāt (prayer) all the nights and observe Ṣaum (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 observe Ṣaum (fast) three days a month, for this will be the Ṣaum (fast) of a whole year." I said, "I find myself able to observe Ṣaum (fast) more." He said: "Then observe Ṣaum (fast) like the fasting of (the Prophet) Dāwūd (David) عليه السلام who used to fast on alternate days and would not flee on facing the enemy."
