 He was famous for his strong rejection of analogical reason, which was accepted by both the Hanafites and Shafi'ites; of juristic preference, a pillar of Hanafite though; of binding consensus, accepted by all of Sunni Islam; and of the hadith supposedly reporting prophetic traditions, accepted by the majority of Muslims in multiple sects.Like other early Mu'tazilites, An-Nazzam was a scripturalist who had no use for hadiths, which he believed were full of contradictions.Nazzam's rejection of consensus as a valid source of law was primarily due to his rationalist criticism of the first generation of Muslims, mainly Abu Hurayra, whom he viewed as possessing defective personalities and intellects.
