The Quran is what told us that their books are corrupt.

When Allah tells us to ask the people of the book, this is referring to the things that we are in agreement in such as the existence of one God, the angels, the messengers, the books, heaven and hell etc.

If their book is not corrupt, let them produce a copy that all Christians agree upon.

The christians allege that their book is not corrupted and that the Quran confirms that where it says ”if you have any doubts with what we have sent to you then ask the people of the book(jews and christians)”And they say had their book been corrupt then the Quran would not havereferred the prophet peace be upon him to their book after all no one refers a person to something that is faulty….. but i know this is wrong interpretation.Kindly clarify the meaning of the above verse and why the prophet was told to refer to their books when the last and final revelation is the GLORIOUS QURAN.
