The Qur'an is given as the book (kitab) to the Jews and Christians together and they read the same thing. Yet, the Qur'an is also the Book (kitab) given to the Arabian people. So, either the Qur'an thinks the Injil and the Torah are the same book given to different people and the Qur'an is the same as them just given to the Arabian people (which shows the Qur'an is false) OR the book that the Jews and Christians read is the bible at large and the Qur'an thinks the Jews read the NT.
