While I would hesitate to disagree with a scholar of Islam like Cameron, Sura 47 contains the ayah : "When you encounter the unbelievers on the battlefield, strike off their heads until you have crushed them completely."
Usually, after a horrible crime, it's the lawyer for the killer who steps forward to assure the public and potential jurors that his client had nothing whatsoever to do with the act.
But when it comes to Muslim terror, that is now the role of political leaders.
“This was not just an attack on Britain – and on our British way of life. It was also a betrayal of Islam and of the Muslim communities who give so much to our country," British Prime Minister David Cameron said. “There is nothing in Islam that justifies this truly dreadful act. We will defeat violent extremism by standing together by backing our police and security services and above all by challenging the poisonous narrative of extremism on which this violence feeds.”
Muslim communities do indeed give so much to the UK, aside from the occasional bombing and beheading, there are the sex grooming gangs, the social welfare fraud and the drug dealing.
It's astounding really. They give so much and get so little in return. Just free homes and jail sentences.
But while I would hesitate to disagree with a scholar of Islam like Cameron, perhaps we should turn to a more expert source.
Sura (chapter) 47 contains the ayah (verse): "When you encounter the unbelievers on the battlefield, strike off their heads until you have crushed them completely; then bind the prisoners tightly." The Qur'anic Arabic terms are generally straightforward: kafaru means "those who blaspheme/are irreligious," although Darb ar-riqab is less clear. Darb can mean "striking or hitting" while ar-riqab translates to "necks, slaves, persons." With little variation, scholars have translated the verse as, "When you meet the unbelievers, smite their necks."
If this is at all ambiguous, let's clear it up for Cam.
The practice of beheading non-Muslim captives extends back to the Prophet himself. Ibn Ishaq (d. 768 C.E.), the earliest biographer of Muhammad, is recorded as saying that the Prophet ordered the execution by decapitation of 700 men of the Jewish Banu Qurayza tribe in Medina for allegedly plotting against him.
Yusuf b. Tashfin (d. 1106) led the Al-Murabit (Almoravid) Empire to conquer from western Sahara to central Spain. After the battle of Zallaqa in 1086, he had 24,000 corpses of the defeated Castilians beheaded "and piled them up to make a sort of minaret for the muezzins who, standing on the piles of headless cadavers, sang the praises of Allah."
Perhaps Cameron will need to see 24,000 beheaded corpses instead of just one.
One of the killers, who according to Anjem Choudary, "Was Just a Completely Normal Guy. He Was Interested in Islam, in Memorising the Koran,” appeared to be a better Koranic scholar than the Prime Minister.
Perhaps Prime Minister Cameron will avail himself of a few lessons on Islam from the London beheader.
