Be mindful of your words and actions even in moments of strong emotion ; Understand the importance of fulfilling one's commitments regardless of emotion state ; Pay atonement for mistakes made due to anger .

In this hadith, the Prophet Muhammad (PBUH) teaches us about anger and vows. He explains that when we are angry, we should not make any vows or promises because they are not valid. Instead, if we do make a vow while angry, then it must be expiated like an oath. This means that if someone makes a promise while angry but does not fulfill it, then they must pay something to atone for their mistake. This teaches us to be mindful of our words and actions even when we are feeling strong emotions like anger so that we can avoid making mistakes or breaking promises unintentionally.
