later than any other verse, ... They merely asserted without proof that one verse was later than another. ... even more surprising is the absence of a single agreed hadith from the Prophet which might be taken to be a certain documentary proof that verse so-and-so is the nasikh of verse so-and-so." This raises the question of whether human scholars deciding what had been abrogating are not introducing a "man-made" element into divine revelation. Non-Muslim John Burton argues that the theory of naskh was an "invention of fiqh scholars", used not to develop fiqh but to validated already existing fiqh doctrine. (Burton is among those in the "mainstream" of the Islamic studies field of fiqh/Islamic law led by Ignác Goldziher and Joseph Schacht who hold that fiqh doctrine did not grow directly and organically from the Quran and sayings and doings of Muhammad but was already established and sometimes in contradiction with the Quran when the theory of naskh was established.) A "careful examination of the Quran itself produces no evidence that naskh of the sort fiqh scholars had in mind is envisioned in or exemplified by the Quran." This sort of naskh would be the "classical" form of abrogation, namely abrogation of rulings but not text as (1. naskh al-hukm dūna al-tilāwa). But if this was the case, would not Q.2:106 read: "Whatever existing ritual or legal regulation We suppress or cause to abandon, We shall bring in its place another superior to it or at least similar to it... " ... instead of what it does say: "What We abrogate (of) a sign or [We] cause it to be forgotten, We bring better than it or similar (to) it." Furthermore, Burton argues (according to Bernard Weiss) that rather than fiqh scholars deciding which of two (or more) conflicting verses should be the basis of a ruling in Islamic law by determining which verse came later, the scholars searched for "text that supported" an already established doctrine of Islamic law and then postulating "a chronology" whereby that supportive text came "later and the non-supportive text earlier". Defense The principle of naskh is acknowledged by both Sunnis and Shī'a, and the vast majority of their scholars accept that there are significant contradictions within the Quran, within the Hadiths, between the Quran and the Hadiths, and that the doctrine of abrogation as revealed by the Quran is necessary to establish Sharia.
