All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

It is not permissible to respect other religions as they disbelieve in Allaah. Hence, it is an obligation to destroy such a book so that it could not be read by people. If lying is the only means to achieve this, then this is permissible. The scholars stated that it is permissible to lie in order to achieve a praised objective which cannot be achieved except by lying.
