Respect your parents and avoid using their names in vain; speak with reverence for God’s name only; use God’s name when swearing instead of anyone else’s name; strive to be mindful of your words at all times .

This hadith is about the importance of swearing by Allah instead of one's father. The Prophet Muhammad was travelling with a troop when he heard Umar ibn al-Khattab swear by his father and he immediately corrected him saying that it is forbidden to do so. He then encouraged him to either swear by Allah or keep silent instead. This hadith teaches us the importance of respecting our parents and not using their name in vain as well as the power of remaining silent when we are angry or frustrated. It also reminds us that we should always strive to use God's name in our speech rather than anyone else's name as it is more respectful and meaningful.
