A detailed account of Mohammed's misdeeds as told by the Koran and Hadith.
Why Muhammed was not a prophet: One who claims to be a messenger of God is expected to live a saintly life. He must not be given to lust, he must not be a sexual pervert, and he must not be a rapist, a highway robber, a war criminal, a mass murderer or an assassin. One who claims to be a messenger of God must have a superior character. He must stand above the vices of the people of his time. Yet Muhammad's life is that of a gangster godfather.
He raided merchant caravans, looted innocent people, massacred entire male populations and enslaved the women and children. He raped the women captured in war after killing their husbands and told his followers that it is okay to have sex with their captives and their "right hand possessions" (Quran 33:50) He assassinated those who criticized him and executed them when he came to power and became de facto despot of Arabia. Muhammad was bereft of human compassion. He was an obsessed man with his dreams of grandiosity and could not forgive those who stood in his way. Muhammad was a narcissist like Hitler, Saddam or Stalin.
He was astute and knew how to manipulate people, but his emotional intelligence was less evolved than that of a 6-year-old child. He simply could not feel the pain of others. He brutally massacred thousands of innocent people and pillaged their wealth. His ambitions were big and as a narcissist he honestly believed he is entitled to do as he pleased and commit all sorts of crimes and his evil deeds are justified.
Why Quran is not from God: Muhammad produced no miracles and when pressed he claimed that his miracle is the Quran. Yet a cursory look at the Quran reveals that this book is full of errors. Quran is replete with scientific heresies, historic blunders, mathematical mistakes, logical absurdities, grammatical errors and ethical fallacies. It is badly compiled and it contradicts itself. There is nothing intelligent in this book let alone miraculous. Muhammad challenged people to produce a "Surah like it" or find an error therein, yet Muslims would kill anyone who dares to criticize it. In such a climate of hypocrisy and violence truth is the first casualty.
