After the spreading of the Internet, and despite the semi-full blockade imposed by the Saudi government against websites critical of religion and politics, I had curiosity and tendency to liberty and exploration of the hidden; so I got into the habit of bypassing the blockade. After some time, I viewed information that was not previously available when governments fully controlled the media and education: What the critics of Islam have published of strong proofs for the humanness of the Quran. And by pondering them, with the ability to understand archaic Arabic.. I attained awareness of the extent of fakeness, and realized the magnitude of the historic deceit. So I left religion on that basis.Over the years.. I gathered the strongest proofs, paraphrased them, added to them, and finally documented them in this ebook, along with my own research and opinions, to arm myself with it in defending my position. Praise and thanks to those who preceded me in discovering and publishing them (Christians and irreligionists), and because of them I knew many of them. These proofs implicate the three Abrahamic religions, as they have the same flaws. And there is no difference between us and the followers of any other religion; the offspring inherit the beliefs of parents through centuries, and they are mere beliefs.. most of which are delusions, built on ignorance and deceit, and enticement and intimidation.Arguments and proofs that the Quran is man-made, not divine, earthly, not heavenly: Many scientific errors (ignorance), modifications (uncertainty), approval of owning slaves (human trafficking), sexual and class discrimination (injustice), sexual abuse of children (pedophilia), temporary marriage (prostitution), raiding, plundering spoils (armed robbery), enslaving women of enemy (rape), slaughtering captives, torture and cutting hands and feet. All of this is proven in the Quran. The details are in this book.To the scholar of Quran I say: "If you do not know, then it is a calamity, and if you know, then the calamity is greater."Dear reader, the Quran says: "Will they not ponder the Quran? Or are there locks upon their hearts?" 47:24 I – This book helps you to do that, if you are among those who prefer facts over delusions; it is directed to anyone who believes in the Islamic belief, and anyone who is interested, in order to contribute to make freedom and dignity come true for all people, and the abatement of physical and mental terrorism; and it is a means of defense, not offense, as its main purpose is to record and explain the reasons that pushed me to leave the religion, and more reasons that would make others leave it or avoid it, and to prove that we left falsehood for the sake of becoming on the right path to the truth.
