Respect God Almighty above all else, be mindful of your words before speaking them out loud and think about their consequences before saying them out loud .

This hadith teaches us the importance of swearing by Allah alone and not our forefathers. The Prophet Muhammad saw Umar al-Khattab in a caravan swearing by his father and told him that it is forbidden to do so. He said that if anyone swears, they must swear only by Allah or keep silent. This hadith emphasizes the importance of respecting and revering God above all else, even our own family members. It also teaches us to be mindful of our words and think before we speak as we are accountable for what we say in front of God Almighty.
