This study illustrates why the language of the Qur'an is miraculous, unique, and evidence of divine authority. The author compares the language of the Qur'an with the language of pre-Islamic poetry, the Prophet's words (hadith), and the language of the Arabs both past and present, to demonstrate that although the Qur'an was revealed in Arabic it was at the same time an Arabic which was entirely new. Original and early Muslim audiences viewed this as miraculous and responded to the Qur'an's words, sounds, rhythms, etc. in a manner consistent with a deeper appreciation of its beauty and majesty which modern ears, trained by familiarity, and despite being surrounded by all manner of dictionaries and studies, are at a loss to capture.
