Nonviolence today represents not merely a moral option but a moral imperative, an existential necessity for humanity's survival on Earth. This paper examines the crucial shift from viewing nonviolence as optional to recognizing it as essential and explores how an inclusive theology of nonviolence can transform Islamic theological discourse and religious thought more broadly. Central to this transformation is the project of "disarming theology," liberating theological frameworks from complicity with imperialistic agendas and nostalgic attachments to violent paradigms. Drawing on Islamic sources and contemporary ethical theory, this presentation demonstrates how a theology grounded in nonviolence can contribute to both religious reform and planetary survival.
