Many Christian missionaries claim the Prophet Muhammad authored the Holy Quran without giving us convincing reasons; in this short article we are going to refute this claim with historical and logical reasons: The Holy Quran can't have been authored by the Prophet Muhammad for the following reasons:  

(1)The miraculous literary style

The Holy Quran was revealed in a unique Arabic literary style that cannot be put under any literary category, its beauty is unexplainable.

It was revealed in the time of the existence of Arabs leading poets, these poets testified to its divine source. The Holy Quran opened challenge to anyone to give a similar verse like its but up till now, though the challenge is still open, no one could challenge the Holy Quran.

The Holy Quran is well-preserved by God, God says in the Holy Quran what means:

We have sent down this Exposition, and We will guard it. (15:9)

All the copies of the Quran, old and new, are the same, no single letter was changes, it is the sole Holy Book that you can read it as it was revealed to the prophet.

(2) The Holy Quran included prophecies

The Holy Quran contains a multitude of prophecies that were fulfilled at the time of the prophet and even now, among the prophecies that have been fulfilled in our modern age is the prophecy of conquering the space.

(3)In the Holy Quran there are scientific statements that are compatible with science.

There are scientific statements in the Holy Quran that addresses both the believers and the non-believers, these scientific statements, despite its great number, have been found compatible with our modern science. These verses prove to the non-believers that there is a Creator who created the universe and that the source of the Holy Quran is That Great Creator.   There are scientific statement about the stages of the universe creation, atom, human creation stages, clouds, seas, the circle of water and so many.

(4)The coherency of each words, lines and chapter

Every word, verse and Chapter has a purpose.

Speaking about the Quran, Goethe says,

"It soon attracts, astounds, and in the end enforces our reverence... Its style, in accordance with its contents and aim is stern, grand - ever and always, truly sublime - So, this book will go on exercising through all ages a most potent influence."

[Goethe - quoted in T. P. Huges "Dictionary of Islam", p. 526]

(5)In the Holy Quran, there are no scientific errors, no absurdities, no superstitions or any anachronism.

(6) In the Holy Quran, there are a few verses that blame the prophet; for example, God blamed the prophet for not answering the question of a blind man while he was busying himself of explaining Islam to some influential peoples. Is there anyone who authors a book then blames himself in it?!

(7) No one could author a book without leaving any effect of his personal approaches; in the Holy Quran there are a few verses that order the prophet to judge some matters in a way different from that he did.

(8) There is no single reference to the tortures or persecutions that the prophet suffered from while imparting God's word. If had been an imposter, he should have recorded his efforts and sufferings.

(9)You cannot find any reference to any of the prophet's wives or daughters by the name while you can find a complete chapter named after "Mary", the mother of Jesus. If he had authored the Holy Quran, he would have included the name of his staunch wife Khadiga, who gave much to Islam. Nor can you find a reference to any of his staunch companions by name; the only reference went to one the slaves whom he freed.

(10)There is a big difference between the wording, phrasing of the hadiths of the prophet and the wording and phrasing of the Quran to extent that you can easily distinguish between them.
