People often say that Dajjal but they mean they respect the right of others to practice their religion & don't want to offend by dissing it, it's just clumsily put. A very common error.
I'd think the likes of Tommy Robinson wouldn't have indepth knowlege of the Qu'ran (he's no relation! When I was single my initials were EDL! I'm now glad I changed my name
),
Most likely he bought some large print illustrated childrens' book giving an outline of the Qu'ran, rather like some childrens' Bibles only the illustrations wouldn't be of people.
Haven't seen the interview with Piers Morgan, Dajjal, but now you've brought it up I'll find it and watch when I can, sounds interesting. Thanks.
