Full implementation of Sharia theoretically refers to expanding its scope to all fields of law and all areas of public life. In practice, Islamization campaigns have focused on a few highly visible issues associated with the conservative Muslim identity, particularly women's hijab and the "hudud" criminal punishments (whipping, stoning and amputation) prescribed for certain crimes. For many Islamists, "hudud" punishments are at the core of the divine Sharia because they are specified by the letter of scripture rather than by human interpreters. Modern Islamists have often rejected, at least in theory, the stringent procedural constraints developed by classical jurists to restrict their application. To the broader Muslim public, the calls for Sharia often represent, even more than any specific demands, a vague vision of their current economic and political situation being replaced by a "just utopia".
