Today, more than ever Muslims need to answer to such questions as: "Who was Muhammad?" "Why is he loved so much by some and hated so much by others?" "Was he really a prophet of God?" "What did he teach?" "Did he live up to his claims?" "Did he encourage war and terrorism?" "What is the truth about this man?" The purpose of this small book is to present facts that are based on historically verified sources and then leave the reader to make his own decision, or if he desires, to investigate the matter further.
