To add to the Islamic perspective, it also has an anecdotal experience to confirm the truth, that God will shown the signs of the soul and "horizons" (translated as universe, but really can be spiritual in meaning):
سَنُرِيهِمْ آيَاتِنَا فِي الْآفَاقِ وَفِي أَنْفُسِهِمْ حَتَّىٰ يَتَبَيَّنَ لَهُمْ أَنَّهُ الْحَقُّ ۗ أَوَلَمْ يَكْفِ بِرَبِّكَ أَنَّهُ عَلَىٰ كُلِّ شَيْءٍ شَهِيدٌ {53}
[Shakir 41:53] We will soon show them Our signs in the Universe and in their own souls, until it will become quite clear to them that it is the truth. Is it not sufficient as regards your Lord that He is a witness over all things?
It also has another argument, that if there are no contradictions in Quran, then it's from God.
So it has three ways to know.
1) Quran being unique implying it's divine.
2) No contradictions implies it's divine.
3) A witnessing of the signs of the self and horizons will make one know Islam is the truth (spiritual witnessing).
As for there being no contradictions implying it's divine, I think it's very weak, but perhaps in it's defence, since people of those times seem to be not perfect in logic, it seems almost bound for them to contradict each other. Perhaps it's not that humanity can never write a book without contradictions but to write such a complicated book, from people of that time, would certainly result in a contradiction.
However, the Quran to me at least seems to have many contradictions.
The reality I feel, is people don't have faith due to any of this, but rather have faith in these arguments or the anecdotal experience, due to faith in the religion that is there for other various factors.
