Stay away from any kind actions which could lead you astray from Allah's path. Be loyal towards Allah and His Messenger.

This hadith speaks about the consequences of treachery on the Day of Judgment. It is narrated from 'Abdullah that the Messenger of Allah said, "A banner will be set up for every traitor on the Day of Resurrection, and it will be said: 'This is the treachery of so-and-so.'" This means that everyone who has committed an act or acts which can be considered as treacherous or disloyal to Allah and His Messenger will have a banner raised in their name on Judgment day. This serves as a reminder to all people to stay away from any kind actions which could lead them astray from Allah's path. Furthermore, this hadith also teaches us about accountability; no matter how small or insignificant our actions may seem now, we are still accountable for them in front God Almighty on Judgment day.
