Why is it so important to certain Muslims to practice beheading?

TERRY’S QUESTION:

What is it with Muslims and beheadings? Where does that (tradition) come from?

THE RELIGION GUY’S ANSWER:

Islam has no hesitation about capital punishment when proper legal procedures are observed and death is hudud (mandatory) under Sharia (religious law). Traditionally this covers such infractions as murder, adultery, homosexual activity, political rebellion, and apostasy, including (under the strictest regimes) conversion to a different religion.

Beheading has a long human history, but what’s remarkable in the 21st Century is its continued use by certain sectors of Muslims while, as the question implies, much of the world regards it as repugnant. Today’s terror sects demonstrate that decapitation remains singularly effective for striking fear into the hearts of subjects and for expressing contempt toward victims. The current “Islamic State” caliphate, a.k.a. ISIS, proudly posts its bloodthirsty videos for another purpose, inspiring excitable youths to join its revolt against traditional religious authorities and attack despised fellow Muslims and non-Muslims.

We also have official incidents -- minus video publicity -- such as Saudi Arabia’s mass execution January 2 of 47 alleged terrorists and political dissidents. The event included beheadings, including of a popular Shia activist, along with deaths by firing squad. Such executions are not unusual for the kingdom. By media accounts, it decapitated some 1,100 defendants in 1984-2004, and at least 57 in 2014 alone, for crimes ranging from drug-running to religious apostasy. Several Muslim regimes that formerly used this method of execution have abandoned it. That leaves Saudi Arabia as unique, and especially noteworthy because it purports to preserve pure and authentic Islamic practice.

Once again, mainstream journalists covering the actions of the Islamic State seem to be struggling to grasp the "why" factor in that old-school "who, what, when, where, why and how" equation.

Why attack Paris, once again? Why hit certain parts of Paris, as opposed to other more famous, if well protected, locations? And what does all of this have to do with that word -- "caliphate" -- that ISIS leaders say is at the heart of everything they do?

Let's walk into this slowly, starting with the top of a July 31, 2014 BBC profile of The Man:

On 5 July, Abu Bakr al-Baghdadi, known by his supporters as Caliph Ibrahim, left the shadows and showed his face for the first time, in a Friday sermon in Mosul, Iraq.

While previous pictures of him had been leaked, Baghdadi had not shown himself in the four years since he became leader of what was then the jihadist Islamic State of Iraq (forerunner of Isis, then the Islamic State). ...

In July 2013, a Bahraini ideologue Turki al-Binali, writing under the pen name Abu Humam Bakr bin Abd al-Aziz al-Athari, wrote a biography of Baghdadi. It highlighted Baghdadi's family history which claims that Baghdadi was indeed a descendant of the Muslim Prophet Muhammad's Quraysh tribe -- one of the key qualifications in Islamic history for becoming the caliph (historically, leader of all Muslims).

It said that Baghdadi came from the al-Bu Badri tribe, which is primarily based in Samarra and Diyala, north and east of Baghdad respectively, and known historically for being descendants of Muhammad.

The key word there, in terms of the mindset of journalists covering ISIS, is "historically," as in the definition of a caliph as "historically, leader of all Muslims."
