Bayat explained it as "a condition where, following a phase of experimentation, the appeal, energy, symbols and sources of legitimacy of Islamism get exhausted, even among its once-ardent supporters. As such, post-Islamism is not anti-Islamic, but rather reflects a tendency to resecularize religion." It originally pertained only to Iran, where "post-Islamism is expressed in the idea of fusion between Islam (as a personalized faith) and individual freedom and choice; and post-Islamism is associated with the values of democracy and aspects of modernity". In this context, the prefix post- does not have historic connotation, but refers to the critical departure from Islamist discourse. Bayat later pointed in 2007 that post-Islamism is both a "condition" and a "project".
French politician Olivier Carré used the term in 1991 from a different perspective, to describe the period between the 10th and the 19th centuries, when both Shiite and Sunni Islam "separated the political-military from the religious realm, both theoretically and in practice".
