Religion of beheading

Beheading, the method that Islamist terrorists have used to execute three hostages in Iraq and Saudi Arabia, is specified by Islamic law, but should be used only in extreme cases, with at least one judge and credible witnesses to a crime, Islamic analysts say.
Others point out that the Koran refers to such a punishment for infidels and that Muhammad oversaw the beheading of several hundred men in his lifetime.
