Much recent scholarship about Islam among youth has tended to privilege so-called political Islam or Islamism and the radicalization of Muslim youth. In this chapter, I shift the focus away from such objects of study to consider a new Islamic organization in Nigeria called NASFAT (Nasr Allah al-Fatih Society of Nigeria) that exhibits some features of a social movement. NASFAT also clearly illustrates the influence of Pentecostalism on Muslim religious practice with some even referring to the organization as 'Islamic Pentecostalism'. NASFAT's founders intended the organization to be both non-sectarian and non-political. Like some other modern Islamic movements, NASFAT has focused on questions of piety and ethics and has been very active in social and economic activities. However, NASFAT's development of business activities, which it has sought to explicitly link with Islam, has been rather distinctive, helping to define it as an Islamic social movement. Given the limited attention to such contemporary Islamic organizations and social movements, which challenge some conventional terms and categories of analysis of Islam, Muslim youth and social movements, the chapter is a preliminary attempt to trace the history of NASFAT and set it within the larger social and historical context.
