As the all-mighty Lord states in various Holy verses, Quran is descended to people in Arabic. The 4th verse in Abraham Chapter says. ”No prophet is sent to any ethnical group to reveal and recite the truth, but speaking in their language.” Definitely, Holy Quran is recited in Arabic. Arabic is the language spoken by the contemporary people to whom Quran is recited. If consider the theory saying that language of ethnic group is not just words and voices but the culture of that specific ethnicity as well. Quran is revealed in the language of specific ethnic group and thus influenced by that cultural ethnicity.
