Application of longitudinal semantics in the explanation of ideological concepts of the Quran: theconcept of Allah in the eyes of Izutsu

Famous Japanese Islamologist, Toshihiko Izutsu, is renowned for his invaluable worksin the field of Quranic research: God and Man in the Quran and Ethico-Religious Concepts in the Quran.By shifting the attitude on the meaning of Quranic expressions and concepts, Izutsu made considerable progress in semantic studies of the Quran, more specifically because he based his studies on semantic knowledge. In God and Man in the Quran, Izutsu attempts to pave the way for the Quran to speak out for itself and interpret itself. Therefore, through using longitudinal semantics, Izutsu investigates the development of ideological concepts of the Quran in genral and the concept of Allah in particular.
