The beheaders are justifying their actions by an appeal to the Qur’an. While there are any number of translations, there is enough ambiguity and blood lust to motivate radical Islamists to follow through with their civilization, destroying worldview.
“Last week, a senior ISIS leader [Abu Muhammad al Adnani] called for attacks in the United States and on Western allies.
Civilians should not be exempt from brutality, he said.
“Do not ask for anyone’s advice and do not seek anyone’s verdict. Kill the disbeliever whether he is civilian or military, for they have the same ruling. Both of them are disbelievers. Both of them are considered to be waging war.”
He gave specifics on how to attack Westerners:
“Rig the roads with explosives for them. Attack their bases. Raid their homes. Cut off their heads. Do not let them feel secure. Hunt them wherever they may be. Turn their worldly life into fear and fire. Remove their families from their homes and thereafter blow up their homes.”
The arrest affidavit reports that the woman claims she asked him why they kill Christians and he replied, “This is just what we do.”
“The victim said Jacob asked her what time she got off work and she replied by asking him in a joking manner if he was going to kill her,’ the detective wrote. “Jacob told the victim, ‘Yes,’ he was going to cut her head off. The victim asked Jacob what he was going to cut her head off with and he said, ‘A blade,’ then told her after he did it he was going to post it on Facebook.”
“The victim said Jacob was serious when speaking and never made any statements that he was joking or playing around.”
The following from the Qur’an could be the justification for these acts of violence. It comes from Dr. Michael Brown’s site – AskDrBrown.org:
