Work hard to achieve something valuable for yourself or society as a whole .

In this hadith, the Prophet Muhammad teaches us that envy is only justified in two cases. The first case is when someone has knowledge of the Quran and recites it during both day and night. This means that if a person puts effort into learning about Islam, then others may feel envious of their knowledge. The second case is when someone has wealth and spends it during both day and night. This means that if a person works hard to earn money, then others may feel envious of their financial success. Both these cases are understandable because they involve people who have worked hard to achieve something valuable for themselves or for society as a whole. However, we should not let our envy turn into hatred or jealousy towards those who have achieved more than us; instead we should strive to work harder ourselves so that we can also achieve success in life.
