Do not tell lies about the prophet .

In this hadith, the Prophet Muhammad is warning us against telling lies about him. He said that if we do so, it will lead us to Hell. This means that if we lie about the Prophet or spread false information about him, then we will be punished for it in the afterlife. It is important for us to remember this and make sure that whatever we say or write about the Prophet is true and accurate. We should also strive to learn more about his life and teachings so that our knowledge of him is correct and based on authentic sources.
