The Arabic form of the Koran is in many ways more important than the text's meaning. After all, Muslims have disagreed over the exact interpretation of Koranic verses as much as followers of other religions have disagreed over their own scriptures. One of the sources of the richness of Islamic intellectual history is the variety of interpretations provided for the same verses. Muslim thinks often quote the Prophet to the effect that every verse of the Koran has seven meanings, beginning with the literal sense, and as for the seventh and deepest meaning, God alone knows that. The language of the Koran is synthetic and imaginistic - each word has a richness having to do with the special genius of the Arabic language.
People naturally understand different meanings from the same verse.
The richness of Koranic language and its receptivity toward different interpretation help explain how this single book could have given shape to one of the world's great civilizations. If everyone had understood exactly the same thing from the text, the religion would never have spread as widely as it has. The Book had to address both the simple and the sophisticated, the shepherd and the philosopher, the scientist and the artist. The Koran also tells us that Muhammad was sent to all the world's inhabitants. In order to present a message understandable to everyone in the world, the Koran had to speak a language that everyone could understand.
