I want to indicate the following points about Koran (Quran):

The Qur’an is the holy book of Islam. We believe that this sacred scripture, which is also called the Koran, is the infallible word of Allah (God), as it was revealed to the prophet Muhammad, Koran is divided into 114 chapters (called Suras ), the Qur’an sets forth the basic requirements of Muslim life, including spiritual, social, and legal codes of conduct, Suras have different sizes and each Sura is divided into ayas (verses).

God supported most prophets with miracles, but all miracles (except Koran) were temporary that they continue for a short time. God supported Mohammed-peace of God upon him- with a lot of miracles, but because Mohammed- peace of God upon him - is the last prophet, Allah(God) give him another special miracle which will continue for ever, this miracle is the Koran.

Koran is the word of Allah that no human can produce some thing like it. Koran is an Arabic book, Arabs are full linguistic people but for more than 14 centuries ( when Koran first appeared) until this moment they can not challenge Koran by inventing any Sura or even an Aya.

Koran is the complete expressivity book, the perfect linguistic book, so Koran it self can not be translated but it's meanings (not it self) are translated to other languages.

Moreover Koran has a strange effect on souls if it heard or read in the true Arabic way. Koran is also full with scientific miracles that is discovered every day leading a lot of famous scientists to believe in Islam, if you are interested you can ask me about that.

This small book will not stop giving evidences that it is the word of Allah.
