In Egypt, a law based on the doctrine of hisba had for a time allowed a Muslim to sue another Muslim over beliefs that may harm society, though because of abuses it has been amended so that only the state prosecutor may bring suit based on private requests. Before the amendment was passed, a hisba suit brought by a group of Islamists against the liberal theologian Nasr Abu Zayd on charges of apostasy led to annulment of his marriage. The law was also invoked in an unsuccessful blasphemy suit against the feminist author Nawal El Saadawi. Hisba has also been invoked in several Muslim-majority countries as rationale for blocking pornographic content on the internet and for other forms of faith-based censorship.
