This study examines the contribution of Imam Al-Shafi'i in positioning the basis of the teori of the verification of hadith in Al-Risalah. The purpose of this paper is to reveal the role of Imam Al-Shafi'i in positioning the accepted standard and the absence of a hadith as a source of Islamic law. The process of data collection is done by examining the theories of hadith submitted by Al-Shafi'i in the book Al-Risalah and displays the analysis of the scholars who commented on the book Al-Risalah. The result of the analysis raises several theories of hadith verification from al-Shaafi'i; i.e. he explained that Hadith must fulfill certain criteria so that it can be accepted or not. Al-Shafi'i also explained the rules on the differences found in Hadith both in terms of text and history, how the law in a hadith can be replaced by another hadith. In addition, Al-Shafi'i made a clear boundary between Hadith, Sunnah and qawl his companions and his position in the excavation of law which is also called Khabar, Akhbâr, Riwâyah, Atsar. This study is very useful for researchers thought Imam al-Shafi'i to be more intact in understanding the contribution of Al-Shafi'i, not only the theory of Usul Fikih and Fikih, but also in the fundamentals of the theory of hadith verification.
