Transmitting the Prophet's Sunnah and narrating Hadīths from the Messenger of Allah (may Allah's peace and blessings be upon him) is a great matter and serious responsibility. The Companions (may Allah be pleased with them) were keen on the accuracy and authenticity of these narrations. In this tradition, Caliph Mu‘āwiyah ibn Abi Sufyān (may Allah be pleased with him) warns his subjects and those around him about the excessive narrating of Hadīths from the Messenger of Allah (may Allah's peace and blessings be upon him) without verification of the reports or differentiation between the Sunnah and Prophetic Hadīths and other reports, lest they might engage in lying about the Messenger of Allah (may Allah's peace and blessings be upon him). Indeed, lying about the Messenger of Allah (may Allah's peace and blessings be upon him) is a sin that is more grave than lying about others. Mu‘āwiyah's warning to the people was during his reign, given the prevalent transmission of reports about the People of the Book and the contents that were found in their books after their countries were conquered. So, he feared that their statements could be mixed with the statements of the Messenger of Allah (may Allah's peace and blessings be upon him). Yet, he excluded the time and reign of 'Umar ibn al-Khattāb (may Allah be pleased with him), saying: "Beware of Hadīths, except those Hadīths during the reign of ‘Umar" i.e., unless you accept and narrate the Hadīths that were known, widely acted upon, and acknowledged during the time of ‘Umar (may Allah be pleased with him). And more worthy among them are those Hadīths that were narrated by ‘Umar (may Allah be pleased with him) himself. Then, clarifying why he excluded Hadīths that were during the reign of ‘Umar (may Allah be pleased with him), he said: "For indeed 'Umar used to make people fearful" by his strength and firmness, as he used to punish those who committed mistakes and beat them with his small staff in order to defend and preserve the rights of Allah Almighty and the matters of His religion, lest the Hadīths of the Messenger of Allah (may Allah's peace and blessings be upon him) might be subject to distortion and alteration. Therefore, Mu‘āwiyah (may Allah be pleased with him) urged the people to refer to the Hadīths that were narrated during that era, given that it was marked by great meticulousness in the narration of Hadīths. This is because 'Umar (may Allah be pleased with him) used to emphasize to his subjects the seriousness of transmitting reports from the Messenger of Allah (may Allah's peace and blessings be upon him). For example, he would require witnesses for Hadīths. So, he regulated this matter, and the people feared his authority and prohibition of hurried narration of Hadīths. As a result, the sound Hadīths were verified, and the Sunan became widely known and distinguished from other texts during his time (may Allah be pleased with him). This does not limit the meticulousness in the narration of Hadīths to the reign of 'Umar (may Allah be pleased with him) only, but it also existed during the Prophet's lifetime and after that, till the era of Hadīth compilation, as Allah Almighty caused to exist those who revised the Hadīths of His Messenger (may Allah's peace and blessings be upon him) and distinguished the sound ones from others and verified the narrations and those who transmitted them, based on precise and strict rules. Mu‘āwiyah's attitude shows his keenness during his time in examining and distinguishing the Prophet's statements from others. The Hadīth points out the merit of ‘Umar ibn al-Khattāb (may Allah be pleased with him) with regard to preserving the Sunnah during his caliphate. The ruler should urge his subjects to seek knowledge and try to verify and distinguish the sound from the unsound..
