Abstract Although conversion is an ongoing religious journey, it is rarely studied as such. This article provides a longitudinal study of conversion to Islam by Dutch women. People who recently convert might firmly hold on to their new convictions, not providing space for doubts and uncertainty, whereas studying the long-term process also gives insights into moments of weak belief, doubts, and ambivalence, or growing faith and spirituality. Not only these internal contestations are important to examine, also the context of the conversion narrative can change over time. Conversion is a contested issue, yet which aspects of the conversion are contested can shift due to societal debates on Islam. This article conceptualizes the conversion experience as a contextual narrative of the ongoing religious transformation of the ‘self’ in relation to different ‘others’ over time.
