"The word for "dog" in the singular occurs in the Koran five times. The statement, "Nation which denies our revelations," occurs five times in the Koran also. Chapter 7:176 is the first time the word "dog (singular)" is mentioned in the Koran, and the first time the statement,, "The nation which denies our revelations," is mentioned. Therefore the example of the "The nation which denies our revelations" is as the example of a dog (Kalb), in the mention or words."
"dog disease" = "infidel disease" = "black winds of death" = "Jihad Falcon" = "cave of darkness" = bioattack = bioengineered pandemic
(another interpretation)
With a pandemic, naturally-occurring or engineered to appear so, literally hundreds of millions could be dead in a matter of months.
You would think mass martrydom on this scale would be unthinkable even to jihadis as it would inevitably go global and kill their families as well.
But we have yet to plumb the depths of their madness.
There are others who have been working on this weapon for years.
Not as unthinkable as those of us in a western mindset would imagine. Remember a few weeks ago of the Palistinian mother who wanted more of her children to become suicide bombers. Rationality is not a part of the jihadi thought.
