A comparative history of idea of Biblical falsification in the Shi'ite and Sunnite exegesis

The idea of Biblical falsification is so widespread among Muslim scholars that it seems believable that once it had not been at existence at all. This paper aims to survey the history of the genesis and development of this idea in the Shi'ite and Sunnite exegeses by using the research method of "history of ideas". This survey shows that this idea has had two different stories in two traditions, but in both of them it has reached a common point simultaneously. The overall image of this path may be explained by the pattern of "silence-murmur-new paradigm", though the details -- including the history of genesis of each level, the reason of transmission from a level to the next, and even the number of levels -- differ in each tradition. This paper tries to compare these two different paths of historical development of the idea depict a detailed image of the story.
