survey of authority and validity of outward aspects of quran (in the light of the teachings of nahj al-balaghah)

the amount of reliability on outward aspects of the quran and the role of traditions in it has been one of the linguistic basics of the holy quran and it has allocated to itself a large volume of principled and hermeneutical subjects. we faced two sets of statements in teachings of imam ali (pbuh). the first category are the evidences that it may be understood from them authority and validity of outward aspects of the quran and their independence in understanding and inference. the second category are the evidences that it is mentioned in them multidimensional nature of the quran and requirement to exegesis of household of prophet muhammad (ahl al-bayt); so it may be understood from them lack of authority and invalidity of outward aspects of the quran and their dependence in understanding and exegesis. criticizing these two understandings, author of this paper believe that after checking the evidences and despairing of them (not necessarily narrative evidences), outward aspects of the quran have authority and validity and it can be trusted to them. this is the subject that it can be understood and derived relying on the teachings of nahj al-balaghah.
