Why are some Muslims intolerant, violent and supremacist? Why do they bully? What spurs them to riot and murder over the silliest things?

To understand Muslims, one must understand their prophet. This psychobiography seeks to unveil the mystery of the prophet of Islam. Historians tell us Muhammad used to withdraw to a cave, spending days wrapped in his thoughts. He heard bells ringing and had ghostly visions. He thought he was demon possessed, until his wife reassured him he had become a prophet. Convinced of his status, he was intolerant of those who rejected him, assassinated those who criticized him, raided, looted, and massacred entire populations. He reduced thousands to slavery, raped, and allowed his men to rape female captives. All of this, he did with a clear conscience and a sense of entitlement. He was magnanimous toward those who admired him, but vengeful toward those who did not. He believed he was the most perfect human creation and the universe's raison d'àªtre. Muhammad was no ordinary man.

This book ventures beyond the stories. Focusing on the "why" rather than the "what," it unravels the mystique of one of the most enigmatic and influential men in history. Islam is Muhammadanism. Muslims worship and emulate Muhammad. Only by understanding him can one know what makes them tick.

Understanding Muhammad begins with a brief history of his life. Muhammad had a loveless childhood. He then passed to the care of relatives who took pity on him and spoiled him. As the result he developed narcissistic personality disorder, a trait that made him a megalomaniac bereft of conscience. Muhammad believed in his own cause. Even when he lied, he felt entitled and justified to do so. Thanks to another mental illness, namely temporal lobe epilepsy, the prophet of Islam had vivid hallucinations he interpreted as mystical and divine intimations. He also suffered from obsessive compulsive disorder, causing his fixations on numbers, rituals and stringent rules. In the addition, he suffered from acromegaly, a disease caused by excessive production of a growth hormone resulting in large bones and odd facial features.

The combination of his psychological disorders and his unusual physiognomy made him a phenomenon that set him apart from ordinary people. His uneducated followers interpreted his differences as signs of his prophethood. Like devotees of all cults, they rose to champion his cause with dedication. By defying death and butchering others they made Islam the world's second largest religion, now the biggest threat to world peace. The author argues that Islam is incompatible with democracy and human rights, and the only way to avert the clash between barbarity and civilization, and a world disaster, is to expose its fallacy and demystify it. "Muslims must be weaned from Islam for humanity to live in peace," says Ali Sina.



A Bold and Daring Masterpiece! The hallmark of a seminal work is that it crystallizes into a single, overpowering coherence its reader's dark suspicions, ephemeral unease, and penumbral stirrings. Understanding Muhammad introduces an organizing principle into what hitherto appeared to be utter mayhem and lethal chaos. Ali Sina's book offers an explanatory scheme. One "a-ha" moment chases another as things fall into place and a causative chain emerges leading all the way from medieval founder to his current day followers and emulators. This blood-curdling tome is a sweeping, thought-provoking, and thrilling historical panorama that weaves seamlessly insights from numerous disciplines: history, mental health, theology, and more.
