This chapter examines the language around harm, focussing on keywords related to the category of violence: jihad, kill, martrydom and paradise. We identify the frequent use of a religious journey metaphor which extremist writers have taken from the Qur’an and reworked to justify killing. A key stage on this path then, is the conceptualisation of jihad as literal fighting and as obligatory, desired by Allah and in is his name. Three representations around killing help to position Muslims as victims, giving a justification for killing civilians, and helping to assuage fears around losing one’s own life as the result of engaging in violent attacks, again by invoking Allah’s authority and approval. Violence is cast as heroic martyrdom and justified as occurring within the context of a war.
