This essay will examine the differences between Western and Muslim notions of blasphemy, as well as discuss scriptural justifications and hurdles for the enforcement of blasphemy laws in the Muslim world. Qur’anic teachings concerning blasphemy will also be compared to the teachings and examples contained within the sunnah. Thirdly, within the few examples drawn from the sunnah, this essay will briefly explore some of the earliest recorded cases of blasphemy in the Muslim world. Further, an exposition on the development of the concept and punishment of blasphemy within Islamic jurisprudence (fiqh) will be proffered, with some specific attention given to the Hanafi School of fiqh in Pakistan and its non-pardonable application of the death penalty against Muslims and non-Muslims. Finally, this essay will examine the observable link between the enforcement of blasphemy laws and Islamic terrorism, both within Muslim countries and beyond. It will be argued that the enforcement of blasphemy laws creates an ‘anti-blasphemy culture’ which has given rise to an increase in the instances of murder and terrorism by Islamist extremists against those believed to be guilty of blasphemy in the Muslim world and in the secular West.
