This book is a means of defense, not offence; as the main purpose of it is to record and explain the reasons that pushed me to leave the religion (Islam), (there isn't any personal reason in them; rather they're information that was not available to us previously,) and to prove that the irreligionist.. left falseness for the sake of becoming on the right path to truth. Religion is belief; and belief is ideas. No idea should be excluded from criticism and skepticism, with full respect for its believers and any noble value ​​it may contain. Criticism of religion is useful, important, even necessary; in order to see the truth as truth so we follow it, and to see falseness as falseness so we avoid it, and for the sake of having the empowerment by rightness substitute the rightfulness by power.
