It might be a good idea to see what the Glorious Qur'an Itself says:
"Verily, We have made this (Qur'an) easy, in thy tongue, in order that they (people) may give heed." XLIV:58
Not only is the Noble Qur'an pleasantly uncomplicated, It is also charming and mellifluous; Its rhythm elevates the spirit of mankind to high levels. Even the allegorical part, which may not always be fully comprehensible, is delightfully stimulating. One important evidence for the miraculous nature of the Glorious Qur'an is the very fact that many wise promises and warnings, glad tidings and admonitions, educational examples and historical events, and highly scientific facts are eloquently explained within simple vocabulary!
