Allah may be hard to understand, but anybody can understand Mohammed. The reason is simple. We have his official biography (called the Sira) and it is a fascinating, ripping read. After Mohammed is born he soon becomes an orphan. He married and became a successful businessman, then a prophet of Allah. He preached Islam for 13 years and converted 150 Muslims. Next he became a politician and jihadist for his last 10 years. When he died every Arab in Arabia was a Muslim. The Sira has religion, plots, spies, war, torture, secret agents, slavery, sex, jealousy and more. It is one of the world's great stories.
Anyone, and I mean anyone, can understand the story of a man's life. Mohammed is the perfect Muslim. When you understand Mohammed, you can easily understand the Koran and you can understand Islam.
This is how easy it is to know Mohammed. The original Sira is 800 pages long and difficult to read. But the book has been made easy to understand in a very short book of only 66 pages, called The Life of Mohammed. Everything is keyed by a small index number at the beginning of the paragraphs that lets you go the official text and confirm it. It is fact-based and is as true as it can be and is a short powerful book.
