The aim of this book is to shed some light on the similarities and differences between these important persons. Although some of the material contained in this book has been drawn from historical sources, the bulk of the quotes were taken directly from religious texts, as well as from the work of renowned theologians. It is worth noting that the relevance of this topic for the present age could not be greater. The religious demographics of many countries are shifting rapidly. Areas that at the beginning of the twentieth century had little to no Muslim inhabitants are now predominantly Muslim. This calls for easy-to-read books on Islam and on the theological and historical relations between Islam and Christianity.  Hence, a comparison between the main figures of Islam and Christianity is of paramount importance, especially when considering the fact that Jesus and Muhammad are widely regarded as the perfect examples of conduct in Christianity and Islam, respectively. Hence, by understanding the characters and goals of these two persons we can gain a deep understanding of the goals and actions of their followers. Acquiring such an understanding is not only advisable, but also indispensable for present-day societies.
