Practice moderation when it comes religious practices such as fasting and praying; do not exhaust yourself unnecessarily by overdoing them .

This hadith is about moderation when it comes to fasting and praying. The Prophet (ﷺ) advised Abdullah bin 'Amr bin Al-'As not to overdo his religious practices, as this could lead him towards exhaustion of his body and weakening of his eyesight. He suggested that if one were able to do so, they should fast three days a month instead of the entire year; this would be equivalent in reward. Furthermore, he mentioned the example of David who used to fast on alternate days but was still able fight in battle without fleeing from the field when meeting an enemy. This hadith teaches us that we should practice moderation when it comes our religious practices; we should not overdo them or exhaust ourselves unnecessarily as this will have negative effects on our physical health and wellbeing. We must also remember that even if we are unable or unwilling for whatever reason, Allah will forgive us for our shortcomings if we are sincere with Him in our intentions and actions.
