The Islamic Dilemma is actually easily refuted
So I have read the book of Abo Isaac on Amazon: The Non-Existence of The Islamic Dilemma
His main point is that the Quran actually nowhere says that it "confirms the Torah" or "confirms the Gospel".
Verses like 3:50, 5:46, 5:48, and 61:6 say that Jesus "confirmed what was present from/of the Torah" and that the Quran "confirms what is present from/of the Book (Torah and Gospel)".
He argues that the verses 3:50, 5:46, 5:48, and 61:6 use the preposition "from/of", in Arabic "مِنْ" pronounced "min".
Something from/of the Torah and Gospel exist in the time of Prophet Muhammad which is being confirmed.
This means that the whole, pristine Torah and Gospel were not available in that era until now. The Quran therefore does not acknowledge any claim of Jews and Christians that the original and complete Torah and Gospel are present. Their remains are present. This is highlighted by that preposition.
This cracks the backbone of the dilemma because the Quran does not recognize any book in its time and future as fully divine. What your thoughts on this
