s of Islam. While many studies evaluate the biographies of these would-be martyrs for evidence of social, psychological, political, or economic strain in an effort to rationalize what are often labeled “suicide bombings,” this book argues that through their legal arguments debating martyrdom-seeking operations, Jihadi-Salafis, including those fighting for al-Qaʿida, ISIS, and their affiliates, craft a theodicy meant to address the suffering and oppression faced by the global Muslim community. Taking as its source material legal arguments (fatwas), texts, pamphlets, magazines, forum posts, videos, and audio files from authors sympathetic to both al-Qaʿida and ISIS on the subjects of martyrdom operations, jurisprudence, and political philosophies, this book reveals that the Jihadi-Salafi legal debates on martyrdom-seeking rearrange the basic objectives (maqāṣid) of the Shariʿa around the principles of maximizing the general welfare (maṣlaḥa) and promoting religion (dīn) above all other concerns—including the preservation of life. This utilitarian turn opens the possibility for formulating a meaningful engagement and critique of Jihadi-Salafi legal interpretation and theories of warfare within a broader, just-war framework. However, as the jurists and propagandists of ISIS demonstrate, this turn also opens the possibility for the utilization of self-renunciative violence as engendering modes of state formation.
