In Iran, "hisba" was enshrined in the constitution after the 1979 Revolution as a "universal and reciprocal duty", incumbent upon both the government and the people. Its implementation has been carried out by official committees as well as volunteer forces ("basij"). Elsewhere, policing of various interpretations of Sharia-based public morality has been carried out by the Kano State Hisbah Corps in the Nigerian state of Kano, by "Polisi Perda Syariah Islam" in the Aceh province of Indonesia, by the Committee for the Propagation of Virtue and the Prevention of Vice in the Gaza Strip, and by the Taleban during their 1996–2001 rule of Afghanistan. Religious police organizations tend to have support from conservative currents of public opinion, but their activities are often disliked by other segments of the population, especially liberals, urban women, and younger people.
