«The Middle Way in Sunnah, Consensus and Differences», in 15 volume set by Abu Bakr Muhammad ibn Ibrahim ibn al-Mundhir al-Naisaburi (d. 318/~921). This work is one of the most important works on Islamic jurisprudence, considered to be an encyclopedia of the jurisprudence of the Companions, the Followers, and those below them (including the four Imams). This book is distinguished from other jurisprudence texts by its advantages, such as its classification as an encyclopedia of jurisprudence, particularly in terms of the doctrines of the scholars and their areas of agreement and disagreement.

The book is divided into jurisprudence chapters. The translation is based on the issues on which there is agreement and the disputed issues falling under the chapter.

Each chapter mentions the doctrines of Companions, Followers, Companions, and the four Imams, citing the hadiths or narrations of each group as proof.

The book of al-Awsat is distinguished by the fact that it records what it receives from the scholars, whether it comes from them to report it, or it comes from their books or from their students, etc. Ibn al-Mundhir is notable in his book because he does not prefer one School of Thought to another, nor does he prefer one School to another. He prefers what he believes to be correct, so he narrates it and follows it. He is also different in the scope of his narration because he produces narrations that you might not find anywhere else. He also discusses the authenticity of the Hadith and chains of its narrations, whether they are true or not, and about the narrators, if they are good or bad. He has quoted in his book other works that have not yet reached us.
