Another misconception most people take is that Prophet Muhammad (PBUH) has written the Holy Quran which is false because the Holy Quran is the word of Allah alone. The Quran is a revelation to the Prophet Muhammad (PBUH).
Quran is God revelations to Prophet Mohamed (peace upon him). These revelations of Quran by God to Prophet Mohamed was through the Angel Gabriel and started in year 610 AD when prophet Mohamed was in Mecca (Makkah) and was by then 40 years old. The revelations continued since then and was completed by year 632 AD (year of death of the prophet).
The long period for full revelation of the Quran (around 22 years) allowed the Quran to be fully memorized and documented by many Muslims. It was recited in the mosque by Prophet Mohamed (PBUH) during the daily five prayers without single letter change. Many Muslims since then until now are memorizing Quran fully without single letter difference. This explains why Quran remains by God will, and will remain by God will, without single letter change.
~Highlighting few issues as follow:
1. Some historians claim that prophet Muhammad wrote the Quran by himself. Arguments against this claim are:
Prophet Muhammad was an illiterate man who had no formal education in any science, language, religious or secular.
2. Quran speaks about a variety of branches of science like: Astronomy, Embryology, Hydrology, Geology, Sociology, Psychology, Oceanography, Law etc. including lots of scientific statements that were validated only recently and were not known in the time of the prophet.
3. It was not known about prophet Muhammad any scholarly tendencies or achievements until the age of forty (when he received the first verses of Quran). So, how this illiterate man suddenly brings about a book like the Quran including an ideological and religious revolution that changed history?
4. Why prophet Muhammad (peace be on him), if he authored the Quran, honor the virgin Mary (May Allah be pleased with her), the mother of Jesus (peace be on him) as the best woman over all women on earth over all ages until day of judgment (an honor that even not offered by the bible) while not mentioning his own family members with a single word and even not mentioning any name of them.?
5. If he had authored the Quran, why he didn't claim this authorship of Quran and consequently gaining higher prestige among his followers who may consider him as a God.
6. Why he mentioned Quran verses that reprimand him (as that of chapter 33, verse 37 and chapter 80 verses 1-3) if he wrote Quran by himself?.
And [remember, O Muhammad], when you said to the one on whom Allah bestowed favor and you bestowed favor, "Keep your wife and fear Allah ," while you concealed within yourself that which Allah is to disclose. And you feared the people, while Allah has more right that you fear Him. So when Zayd had no longer any need for her, We married her to you in order that there not be upon the believers any discomfort concerning the wives of their adopted sons when they no longer have need of them. And ever is the command of Allah accomplished.

1- The Prophet frowned and turned away
2- Because there came to him the blind man, [interrupting].
3- But what would make you perceive, [O Muhammad], that perhaps he might be purified
