Exercise restraint when taking action against wrongdoers; Wait for permission from God before doing so; Show respect and mercy towards those with physical disabilities or defects.

This hadith is about the reward that Allah has promised to those who exercise restraint and kill the people of an-Nahrawan. 'Ali mentioned this promise on the lips of Prophet Muhammad, which was confirmed by 'Abeedah. This hadith teaches us that exercising restraint is important in order to receive rewards from Allah. It also shows us that we should be patient when it comes to taking action against wrongdoers, as we should wait for permission from God before doing so. Furthermore, it reminds us that even if someone has a physical disability or defect, they are still deserving of respect and mercy from others.
