As for the fact that the Quran is a miracle because of its linguistic beauty and the fact that the Prophet is illiterate do subjected to question by non-Muslims, simply because beauty is in the eye of the beholder.
Its not just about that. Its the fact that the Quran contains NO mistakes, no contradictions.
Do they not consider the Qur’an (with care)? Had it been from other Than Allah, they would surely have found therein Much discrepancy. (Quran 4:82)
Not only that, but what about the scientific accuracy of the Quran. They’ve actually hosted conferences with non-muslim scientists to discuss the topic of Quran and science. Some of the scientist actually converted to Islam, and if they did not, they said something along the lines of “this book can not be from any normal human being”

Say: “The (Qur’an) was sent down by Him who
knows the mystery (that is) in the heavens and the earth: verily He is Oft-Forgiving, Most Merciful.” (Quran 25:6)
This book actually lives in the hearts and minds of many Muslims around the world…to the extent that people have memorized the entire book (over 10 million people) and the rest of us who have memorized large portions of it. WHat other book can claim that?
But We have indeed made the Qur’an
easy to understand and remember: then is there any that will receive admonition? (Quran 54:22)
Its a miracle to me, because it guides in a way that really nothign else could…
Verily in this (Qur’an) is a Message for people who would (truly) worship Allah. (Chapter #21, Verse #106)
This is the Book; in it is guidance sure, without doubt, to those who fear Allah. (Quran 2:2)
Do they not then earnestly seek to understand the Qur’an, or are their hearts locked up by them? (Chapter #47, Verse #24)
I can not make your heart open to the Quran, that is for Allah alone, but I leave you with this
And to rehearse the Qur’an: and if any accept guidance, they do it for the good of their own souls, and if any stray, say: “
I am only a Warner”. (Quran 27:92)
