Stay true to your word, Do good deeds, Be honest with others.

This hadith speaks about the consequences of betrayal on the Day of Judgment. It is said that Allah will set up a flag for every person who has committed betrayal and it will be announced to all. This means that everyone will know about their wrongdoings and they won't be able to hide from it. The hadith also teaches us that we should always stay true to our word and not betray anyone as we don't want our wrongdoings to be exposed in front of everyone on the Day of Judgment. We should strive to do good deeds so that we can receive rewards from Allah instead.
