A critical study on " Cambridge Quran Instruction" about Tashri system in Quran

The most fundamental presupposition in Quranic Studies from orientalist researchers view is that this book is not inspirational and is affected by the environment's culture. According to this an orientalist – Alexander Nisch – studied Quran incompletely and without considering its language and accurate witnesses in his book entitled "Cambridge Quran Instruction". By an analytical look at Quran understanding criteria and critical – analytical point of view these conflicts and divergences can be disproved and the completeness of Quran can be verified by Quran Tashri’ system.
