This book is considered one of the most significant works for Shafi'i followers, as it compiles hadith evidence for the school of thought, drawing them from authentic collections and sunan. It outlines the routes and reasons behind disputed ones, and why Al-Shafi'i relied on them if disputed, also addressing others like Al-Tahawi of the Hanafis. Al-Bayhaqi further elaborated on the views of the followers and those after them like Abu Thawr, Al-Hasan, and Ahmad, arranging it according to Al-Muzani's order. At times, he presents the old sayings of Al-Shafi'i. The book includes some annotations on hadith extraction, scholar biographies, and references such as 'Al-Umm'.
