Yes, it's about Islam. Abz, the Pakistani Muslim terrorist who took part in the London attack, was a committed and devout Muslim.
Ken Chigbo, 26, who lives in the same building, described him as "really sociable" and said the killer had invited him to a barbecue just last week.
"I know he was quite a devout Muslim, I heard him talking about the Koran," said Mr Chigbo.
"He would preach to young Muslims at the flat.
"Sometimes up to six people quite regularly.”
"He began stopping his neighbours in the street and asking them if they had been saying their prayers and when they had been to the mosque."
The emerging profile of one of the London Muslim terrorists makes it clear that despite the usual denials "irreligious", "argued with the Imam" that we get after every attack, he was a devout Muslim who cared a great deal about propagating his religion.
Erica Gasparri, an Italian mother of three who lived close to him, claimed she had reported him to Barking police two years ago, after he began “brainwashing” her children at a local park. She said she had confronted him after her two children came home and said: “Mummy I want to become a Muslim.”
She said the police had told her the information had been passed to Scotland Yard but she had heard nothing more.
Ms Gasparri said: “He was trying to radicalise the children, he would go down to the park and talk to them about Islam. He also came to the houses and gave the kids money and sweets during Ramadan.”
"He told me he would do whatever is required in the name of Allah... I would be prepared to kill my mother."
Instead he killed some non-Muslims.
