10:40
وَمِنْهُم مَّن يُؤْمِنُ بِهِۦ وَمِنْهُم مَّن لَّا يُؤْمِنُ بِهِۦ ۚ وَرَبُّكَ أَعْلَمُ بِٱلْمُفْسِدِينَ
And of them are those who believe in it, and of them are those who do not believe in it. And your Lord is most knowing of the corrupters

Tafsir
Ibn Kathīr (abridged)
The Qur'an is the True, Inimitable Word of Allah and It is a Miracle
The Qur'an has a miraculous nature that cannot be imitated. No one can produce anything similar to the Qur'an, nor ten Surahs or even one Surah like it. The eloquence, clarity, precision and grace of the Qur'an cannot be but from Allah. The great and abundant principles and meanings within the Qur'an -- which are of great benefit in this world and for the Hereafter -- cannot be but from Allah. There is nothing like His High Self and Attributes or like His sayings and actions. Therefore His Words are not like the words of His creatures. This is why Allah said:
وَمَا كَانَ هَـذَا الْقُرْءَانُ أَن يُفْتَرَى مِن دُونِ اللَّهِ
(And this Qur'an is not such as could ever be produced by other than Allah) meaning, a book like this cannot be but from Allah. This is not similar to the speech uttered by humans.
وَلَـكِن تَصْدِيقَ الَّذِى بَيْنَ يَدَيْهِ
(but it is a confirmation of (the revelation) which was before it,) Such as previous revelations and Books. The Qur'an confirms these books and is a witness to them. It shows the changes, perversions and corruption that have taken place within these Books. Then Allah said,
