Actually, it's quite explainable. Unlike the Bible, the "official" version of the Koran has always been the original text in the original version of Arabic spoken in the 7th century. Since it was written down at the time without having to rely on decades or even centuries of oral tradition, as was the case with the Christian and Hebrew scriptures, it's understandable that the text has remained unchanged. Once you start translating something into different languages, that's when the unavoidable changes start working their way in. So, I agree with you that it's not "miraculous" in any way, but it is a fascinating and important archaeological find.
