That is no fact. For I have searched for days for this reference that says so and I find nothing. I personally follow no Imam or sect or nation even. I am my own person with my own mind and I am educated. I am a man of science first and foremost and a physician. And i hate nothing more than Islamic extremism. And this dude he has called for Islamic extremism and he does not base it on any facts.
I am quite knowledgeable on him and have seen many of his lectures that I found quite funny. And I also hate 90% of all world Imams including Saudis by the way. So it is not personal.
