the arrivals never mentioned anything abt hadhrat abubakr, umar, usman (ra) being with dajjal or anything about them. Infact they tried to step away from sunni-shia differences and spoke about unity, a whole episode dedicated to this very point.
as far as cooked up story is concerned, yes there are many things mentioned that are new to ppl, architecture n energy, energy portals on earth to open for dajjal to enter into this world, one wd have todo their own research to figure out if any of this is real. but governmental powers trying to control the world, freemasonry, illuminati, wars etc., these are not just cooked up stories.
