Islam has rapidly grown to become the second largest religion in the World, with about one billion adherents. In this book we will propose three things: To clearly state the fundamental belief of Islam concerning God, creation, prophets, Muhammad, the Koran and salvation. Also, to respond to basic beliefs in God, Muhammad and the Koran. And finally to examine the evidence for the Christian counterclaim. The authors, one from the occident and the other educated as Muslim, got information from the primary source of each religion, above all the Bible and the Corán, as well as teachers of each religion. 346 pages
