The Quran confirms the Bible, but the Bible in no shape or form confirms the Quran. When Muslims desperately postulate the corruption of the scriptures, we can rightfully deduce that this isn't a notion of their scripture and more a product of their acknowledgment that their text contradicts the scriptures itself and therefore requires a need for them to discredit the scriptures with no sound justification. This isn't even an argument from their text. As a matter of fact, their argument contradicts their own text.
When you have an understanding concerning the History and the translation and transliteration of scriptures, their argument is incognizant, to say the least in its attempt to credit their writings over the scriptures which have the most manuscriptural evidence than any other book on earth. What is also quite incredible taking that into account is that the Abrahamic religions do not adhere to the literature of scriptures themselves and instead engender alternate doctrine and philosophy instead of manipulating the scripture itself.
Discern the following passages from their Qaran confirming the solidarity towards the scriptures of the true prophets of the God of Abraham, Isaac, and Jacob who is undeniably called YHWH. We could easily counter-argue that versions that existed then, exist now, the Septuagint for example, and other newer translations were predicated on bibles that existed at that time also.
It appears some people don't believe in their own writings...
