Gary Miller* search about what is the point of the perfect balance of the Quranic words? he said that : it shows the author of the Quraan whom was Allah was well aware of the distinction between using words and mentioning words, a fine logical point. But more than that, it indicates the preservation of this book.
Millar said :After giving a lecture on the subject of the Qur'an , I touched on some of these subjects and a questionnaire from the audience afterwards said: "How do we know we still have the original Qur'an. Maybe pieces of it have been lost or extra parts been added?" I pointed out to him that we had prettywell covered that point because since these items, the perfect balance of words in the Qur'an, have come to light only in this generation, anybody who would have lost the portion of this book, hidden some of it, or added some of their own would have been unaware of this carefully hidden code in the book. They would have destroyed this perfect balance.
It is interesting to note too that, well, such a thing might be possible to organize today by the use of a computer to coordinate all words so that whatever thought you might have as to a meaning of a sentence or however you might construe an equation out of a sentence, you could check for yourself and the book will always have the balance of words.
Example
We are told in the Qur'an that no questionnaire will come to the Muslims with the question for which a good answer has not been provided, and the best explanation for whatever his question. This verse says: "For everything they say we are given something to go back to them and reply." (25:33
We looked again to the index of the Qur'an and we found the word, qalu (they say), is found three hundred and thirty-two times. Now, what would be the natural counterpart? The Arabic word, qul, which is the command 'say' and you will find at the index it also occurs three hundred and thirty-two times.
