In my opinion, Arabic being the "language of god" is part of the proof that the god that is depicted in Islam (or any other language) does not exist. What kind of god sends his message in a form that is open to interpretation?

But lets talk about Arabic. I LOVE the language. Its the most beautiful and poetic language I know (as eightbitsamurai mentioned too). It is a rich language with many words. I used to love our Arabic literature classes at school. I admit, I wasn't that good in Arabic, but it is a beautiful complex language. Which is also a weakness when it comes to Qur'an.

Many words used in the Qur'an are old words that aren't used in day to day life. A fun example is the word Banana. Which is mentioned in the Qur'an and means finger, and is believed to be the source of the word Banana that we know in English, but back to topic. As old words are used, for some words the exact meaning is not clear or has been lost. So eventually, it will come to misinterpretations. And as we know, its those fine differences that have the biggest influence.

The way I read the Qur'an lead me to the conclusion that its not the scripture I want to live my life according to. It is however possible that others decide that it sounds right to them. Some differences are cultural ones, others are linguistic. Either way, we got to figure out how this is going to work out in the future.
