This is straight out of the Qur’an, which says that Abraham gives an “excellent example” to Muslims when he tells his pagan family that there is now “enmity and hatred” between them and him until they worship Allah alone (60:4).
And: “O you who have believed, do not take your fathers or your brothers as allies if they have preferred disbelief over belief. And whoever does so among you – then it is those who are the wrongdoers” (9:23).
The same goes for mom.
“ISIS twins stab mother to death in anger at her opposition to terror group,” by Tom Batchelor, Express, June 27, 2016 (thanks to David):
TWIN brothers have brutally stabbed to death their mother and seriously injured their father and brother over a disagreement about their allegiance to Islamic State.
The killing in the Saudi Arabian capital is believed to have been sparked after the family fell out with the brothers over their support for ISIS.
The unnamed mother reportedly objected to her sons’ plans to travel to Caliphate in the Middle East to join the jihadists battling US-backed forces.
She was reportedly attacked after telling the 20-year-olds she would report them to the Saudi authorities if they did not cancel their trip.
Khalid and Saleh Al Areeni were named as the perpetrators who carried out the attack in their family home in Riyadh on Friday.
Detectives believe the young men used meat cleavers to first stab their mother before chasing their father and elder brother, who were injured but not fatally wounded.
Believing all three family members to be dead, the two men fled in a stolen car.
