Fuzzy logic in Quran: Confusion of Mustanbat and Mansus

Ali Wahidiyan Kamyad claimed in an article named “Methodology of Usage of Fuzzy Logic in Islamic View” that fuzzy logic is a part of the logic of sacred Quran. This claim was supported by a group of researchers, while it seems that the evidences to prove it are incomplete. So it seems necessary to study the main claim again. What will be come at the continuing contains some critiques to this claim with respect to the Quranic evidences for which has been given. Besides some partial critiques to the correspondence of the Quranic examples which are claimed to be corresponded to the fuzzy argument given, it will be shown that there is a main fault in the claim that Quran has used in some verses the fuzzy logic which is based on a confusion of what is explicitly occurred in the passage as an argument (Mansus argument) and what is in ascribed to the passage by the reader (Mustanbat argument).
