Practice moderation when it comes to religious practices such as fasting and praying; strive for balance between spiritual life & physical life; take care of your body's needs & those around you; observe fasts regularly but don't overburden yourself with too much fasting or praying at night without rest or sleep .

This hadith emphasizes the importance of moderation when it comes to fasting and prayer. The Prophet Muhammad (peace be upon him) advised Abdullah b. 'Amr to observe fast for three days every month, as this would be a perpetual fasting that would not overburden him. He also suggested observing the fast of David, which was one day of fasting followed by one day of breaking the fast. The Prophet Muhammad also reminded Abdullah b. 'Amr that his body has its own needs, as well as his eyes and wife, so he should not overburden himself with too much fasting or praying at night without rest or sleep. This hadith teaches us that we should practice moderation in our religious practices so that we do not become overwhelmed or exhausted from them; instead we should strive for balance between our spiritual life and physical life so that both are taken care of properly.
