Perform extra prayers and fastings beyond what is required; strive for excellence in all aspects of life; build a strong relationship with Allah SWT through worshiping Him; be mindful of your actions even when you have fulfilled your obligations.

This hadith from Prophet Muhammad (PBUH) advises Muslims to perform extra prayers and fastings beyond what is required of them. He recommends that the best prayer after obligatory prayers is night prayer, also known as Tahajjud. Additionally, he suggests that the best fasting after Ramadan should be done in Muharram. These extra acts of worship are encouraged by Islam as they bring one closer to Allah SWT and help build a strong relationship with Him. It also teaches us to be mindful of our actions even when we have fulfilled our obligations so that we can strive for excellence in all aspects of life.
