At a time of terrorist actions, the civil wars in Afghanistan and in Iraq as well as the caricatures of the Prophet and Pope XVI’s speech about violence in Islam, it is urgent for the Islamic academic community to speak about a major issue: the notions of peace and war in Islam.<br /> This paper will explore and analyze these notions, putting an emphasize on Islam as a religion of peace promoting human rights and humanitarian values; the author will of course approaches and presents the explanations as to why Islam is a religion of violence, only to dismiss these arguments. There are indeed authors presenting Islam as a religion of violence that carries deep inside the seeds of hatred, racism and many other values that are against human rights. These authors are usually Orientalists. This paper will explain who and why these theories are wrong. Then there are extremist groups presenting distorted interpretations of Islam as to justify massive killings (terrorism, WMD, suicide attacks); the author of the paper will take few examples as to explain how these movements rely on distorted and nihilist views of Islam.
