I don't know and I don't watch the videos.
I know we are living in the times of the fitnah, perhaps entering the great fitnah times. Only dajjal is not yet here physically.
Everything we read in the mainstream media about world affairs are manipulated information, lies pretty much. It is all to set a scene, propaganda.
Unfortunately, islam is the number 1 target. It is the avowed promise of Syaitan to lead man away from the path to Allah.
He is keeping to his vow. Look at the world today, is it easy to remember Allah? Is it easy or convenient to do His bidding? Can we 'trust' Him to take care of us? Are we capable of 100% submission?
So much fear they've put in us, so much doubt planted into our selves, insecurities and such,, they put it all out there, we come running into their open arms.. . ('They' meaning the devils (Syaitan's) army).
They have infiltrated the islamic clergy, incited bloodshed of the holy prophet's s.a.w sahabah's and cause the split of the ummah. Like what Paul did to the teachings of Jesus pbuh, similar thing also at play in islam. Only the Quran (unchanged) and sunnah has kept islam consistent, regular prayers, fasting, Hajj, and charity, maintaining the Abrahamic tradition of circumcision. No alcohol, no sex before marriage, modesty, intermingling, gambling, polygamy, inheritance all still unchanged since the times of the holy prophet s.a.w. But the devil's army are not done yet, they have chipped away, and are chipping away at it still, dividing the ummah and turning the world against Islam.
For me, the bottom line is, I don't believe 911 or IS were planned and executed by islamic organisations. It is all propaganda.
Hence, it wouldn't surprise me if something similar were the truth. But for now it remains more on gossip level.. not even 'grapevine' in my books.
