The Koran is the be-all and end-all of Islam.
When you read these passages from the Koran, please bear in mind the sacrosanct nature of every word in the Koran for all Moslems — even if they have never read the Koran and even if they do not follow the Koran in their daily lives. The problem is that many Moslems will follow the injunctions of the Koran. Also bear in mind that the following passages from the Koran, among others, are taught and preached every day in every mosque in the world including the one in your neighborhood.
