The first attempt to collect Hadith, the sayings and actions of Prophet Muhammad (peace be upon him), was made during the reign of Umar ibn Abdul Aziz. Umar ibn Abdul Aziz was the eighth Umayyad caliph and is known for his piety and efforts to reform the administration of the Islamic state. He ordered scholars to collect and authenticate the sayings and actions of Prophet Muhammad (peace be upon him) to ensure their preservation and prevent the spread of false or fabricated reports. This collection of Hadith is known as "Mishkat al-Masabih" and is considered one of the earliest compilations of Hadith in Islamic history.
