You can find opinions about Islamic doctrine in the main stream media, but no facts. That is because they do not study the only foundation of knowledge about the true nature of Islam—Mohammed and Allah.
This self-study course is based on three of the Islamic source texts: the Koran, the Sira (biography of Mohammed) and the Hadith (his traditions). If your knowledge comes from these original texts, it can be verified and your understanding is on firm ground.
The Koran and all Islamic texts are difficult to read by design. But, when the artificial language is stripped away and replaced by simple English, the results are astounding.
We learn that the Islamic ethical system is based on dualism—one set of rules for Muslims and another set of rules for non-Muslims (Kafirs). We find out that Mohammed was a slave trader, an abuser of women and a warlord.
Islam as a religion was a failure. Only when Mohammed turned to jihad and politics, did he have any success.
