What is the way to confront the hostile campaigns that promote the book "The True Furqan," which attacks Islam?

The summary of the answer is: The book "Al-Furqan Al-Haqq" was written by its authors to replace the Qur'an. Muslims must be aware of the cunning of their enemies and adhere to the Qur'an and Sunnah (definition), applying their teachings and inviting others to them, especially those in positions of authority, in fulfillment of the Almighty's saying: "O you who have believed, protect yourselves and your families from a Fire whose fuel is people and stones." (Quran 66:6). It is also necessary to warn against this book and expose the true purpose behind its publication and the identity of those responsible for it.
