The Conventional Property of Quranic Language

The conventional property of Quranic language is one of the most remarkable theories in Quranic Language. Using a rational-analytical method and due to the restrictions of the custom language, the present study analyzes this theory. The findings show that the following three perceptions from Quran are rejected and incompatible with the attributes of Quran: 1. Custom (as harmony of Quran with the audience) 2. Custom (as revelation at the level of people`s understanding) 3. Custom (as revelation based on untrue examples). However, if the custom of Quranic language benefits from the principles and attributes of the audience`s language, it is a defendable issue. The language of Quran is custom when expressing the practical principles. Specially under the conditions that there is no negligence, conflict and weakness in the level of the concepts but not in all the verses. Using trope, allusion and metaphor doesn’t make the language of Quran custom. Speaking with the language of the ordinary people in revelation does not mean that the culture of that era is reflected in Quran, it means that historical, geographical and cultural incidents of the society at the time of revelation is reflected freely and based on a true refinement.
