Why did the Arabic language spread with Islam?
Arabic, as the language of the Quran, has always had a special status amongst all Muslims. Muslims, throughout the Islamic world, strive to study Arabic in order to be able to comprehend God’s message as revealed in the Quran. The continued flow of Arabic speakers from the Peninsula gave them access to authentic models, which facilitated learning the language. In addition, the indigenous populations of the lands that have fallen under Muslim rule have realized that learning Arabic is politically and economically advantageous to them.
