Bill Warner PhD - Only One Islam

We hear a lot about different kinds of Islam. How many kinds of Islam are there and which are the correct ones? What is the criteria of choosing the true Islam? We have to start with another question: what is Islam? It turns out to be very simple. Islam is the doctrine found in the Koran and the Sunna of Mohammed. Everything found in the Koran and Sunna is Islam and if it is not found in Koran and Sunna, it is not Islam. Once you know what Islam is, it is easy to talk about the different kinds of Islam.
