This is an English translation of Imam al-Barbahari's classic work, «Sharh as-Sunnah». The book consists of 170 points on different aspects of the Muslim creed. Extensive notes have been provided, giving relevant passages of the Qur'an and authentic sayings of the Prophet. Ample sayings of the early scholars have also been included. In every age, there has been a noble company of scholars who stood firm and expended great efforts in defending the Book of Allah and the Sunnah of His Messenger and in refuting the people of innovated beliefs, innovation, deviation and misguidance. At the head of them towards the end of the third century and the beginning of the fourth was the Imaam who aided the Sunnah and subdued Abu Muhammad al-Hasan ibn 'Alee al-Barbahari.
