Verify sources before accepting them as true teachings from Prophet Muhammad (PBUH).

This hadith emphasizes the importance of verifying the reliability of narrators when transmitting ahadith. It is essential to ensure that the source is trustworthy and accurate in order to preserve the integrity and accuracy of Islamic teachings. In this case, Yazid b. Hurmuz was used as an example for reliable narrators who can be trusted to accurately transmit ahadiths from one generation to another. It is important for Muslims to be aware that not all narrations are equal in terms of reliability and accuracy; therefore, it is necessary to verify their sources before accepting them as true teachings from Prophet Muhammad (PBUH). By doing so, we can ensure that our understanding and practice of Islam remains true to its original form without any distortions or misinterpretations along the way.
