Abd al-Rahman al-Awza'i (88/707 - 157/774) was known as the unique scholar of his time and the imam of his era. This was acknowledged by leading scholars, who considered him the founder of a school of thought and the leader of a school of thought. However, his works have been lost, and we find only a small number of his works scattered throughout the books of the imams, such as al-Umm by al-Shafi'i, Ikhtilaf al-Fuqaha by al-Tabari, and others. In honor of the religion of this great imam and his generosity to Muslims, the author collected his narrations and arranged them according to the books of jurisprudence. This book is a comprehensive account of the doctrine of a great imam of the Muslims.
