Remain steadfast in your faith even when faced with difficult circumstances or temptations; strive to stay true to your beliefs no matter what happens around you; obey Allah's commands without hesitation; accept Allah's verdicts without question; remain faithful despite any external influences.

This hadith narrates an incident between Abu Musa and Mu'adh bin Jabal, where they encountered a man who had embraced Islam but then reverted back to Judaism. When Mu'adh asked what was wrong with the man, Abu Musa replied that he had embraced Islam but then reverted back to Judaism. To this, Mu'adh said that he would not sit down unless the man was killed as it is the verdict of Allah and His Apostle. This hadith teaches us about how serious reverting from one's faith can be taken in Islamic teachings, as well as how important it is for Muslims to remain steadfast in their faith even when faced with difficult circumstances or temptations. It also serves as a reminder for us all that we must always strive to stay true to our beliefs no matter what happens around us or what other people may say or do.
