The Crisis of Islam: Holy War and Unholy Terror is a book written by Bernard Lewis which 'in particular traces the key events of the twentieth century that preceded to today's violent clashes.'(Lewis) Lewis clearly and comprehensively highlighted the key events that explain the choices that must be made by people of the Islamic faith. They must determine whether their religion will take its place alongside other religions in a global community, or whether it will return to conflict with non-Muslim nations. Islam is a religion that most Americans don't understand but still have strong feelings about. To clarify things, Islam is a monotheistic, Abrahamic religion written in the Quran, a book considered by its believers to be the exact word of God. They also consider it to be the last prophet of God through the teachings and example of Muhammad. They refer to their god as Allah. The basis of Islamic life is centered on Allah, to whom one must be submissive and served. They believe that previous messages and revelations have been partially misinterpreted or altered over time as cultures and languages ​​of translation evolved, but they consider the Arabic Quran to be Allah's unaltered and final revelation. The religion is practiced with the five pillars of Islam, which are basic concepts and required acts of worship. The first is the testimony of the oneness of God: the statement "There is no God but Allah and Muhammad is His prophet." The second is Prayer. The prayer must take place at least five times a day, and must be done by bowing and facing Mecca. Furthermore, everyone must stand in a straight line and if women come, even if they are not forced, they must stay behind the men. The third is giving to charity. 2.5% of annual income is generally… half the paper… the culprits can be justified in terms of Islam. He answers directly to the point: no. Lewis clearly and thoroughly outlined the key events that explain the choices that people of the Islamic faith must make. This document has highlighted just a few of the many key events. Lewis says, “Most Muslims are not fundamentalists, and most fundamentalists are not terrorists, but most terrorists today are Muslims and proudly identify as such.” He also expertly points out: “Terrorism requires only a few. Obviously the West must defend itself by whatever means are effective. But in devising the means to combat terrorists, it would certainly be helpful to understand the forces that drive them.” (Lewis. Introduction) In the end, I agree with and congratulate Bernard Lewis in pointing out that the acts of small groups of radicals.
