Qur'an is words of our Lord, God and Creator, Allah, it cannot be wrong, cannot be altered, and has all the benefits for humanity as was told in Qur'an: -"A Book whose verses have been detailed, an Arabic Qur'an for a people who know"-"Indeed, those who disbelieve in the message after it has come to them... And indeed, it is a mighty Book."-"Falsehood cannot approach it from before it or from behind it; [it is] a revelation from a [Lord who is] Wise and Praiseworthy."-"And if We had made it a non-Arabic Qur'an, they would have said, "Why are its verses not explained in detail [in our language]? Is it a foreign [recitation] and an Arab [messenger]?" Say, "It is, for those who believe, a guidance and cure." And those who do not believe - in their ears is deafness, and it is upon them blindness. Those are being called from a distant place."
