In an article titled, "Jews and Christians under Islam Dhimmitude and Marcionism*" by Egyptian-born British writer and political commentator, who writes about the history of non-Muslims in the Middle East, Bat Ye'or:
" According to the theory of jihad, inhabitants of the lands of war (dar al-harb) are infidels to be combated because they oppose the establishment of Islamic law in their countries. As enemies of Allah they have no rights: they themselves and their property become licit (mubah) for all Muslims. As the opportunity arises they can be taken as slaves, kidnapped for ransom, robbed or killed. War is waged against them to Islamize their territory which, according to the will of Allah, must belong to the Islamic community. If they resist, Islamic law provides for the deportation or massacre of the men and the enslavement of women and children. "Some observers suggest Islamism's tenets are less strict and can be defined as a form of identity politics or "support for [Muslim] identity, authenticity, broader regionalism, revivalism, [and] revitalization of the community". Still others define it as "an Islamic militant, anti-democratic movement, bearing a holistic vision of Islam whose final aim is the restoration of the caliphate".
Attributes of sharia law supported by many Islamists include "enforcement of Islamic punishments, including prohibitions on charging interest on loans, playing music, showing television", and enforcing traditional dress and prayer attendance.
