This collection of papers by Imam Rashied Omar provides the reader with a deeper understanding of the Islamic ethics of violence and peace and situates extremist acts within concrete socio-historical and political contexts. The papers examine the major ethico-legal principles on Peace and War in Islam and apply these to analyse the theological justifications and political motivations of contemporary Muslim extremist movements. The papers also suggest possible ways in which we can mitigate the spread of Muslim extremism by identifying Islamic resources for peacebuilding and effective strategies for social justice.
