Fast during Ramadan or other days prescribed by Islamic law; Strive to please Allah through your actions; Have faith and hope in Allah's mercy and reward for your good deeds; Break your fast with joy.

The hadith narrated by Abu Hurairah states that fasting brings joy to a person both in this world and the hereafter. This is because when one fasts, they are rewarded with joy when they break their fast as well as when they meet their Lord. This hadith encourages people to fast, as it shows that there are two great rewards for those who do so. It also teaches us that we should strive to please Allah through our actions, such as fasting, so that we can be rewarded with His pleasure in the afterlife. Furthermore, it reminds us of the importance of having faith and hope in Allah's mercy and reward for our good deeds.
