Who is the army of the black flag? / Who are the Abdal?

I have long held the view that the authentic armed Islamic resistance that is resisting occupation and brutal oppression in Afghanistan, Iraq and elsewhere in that region constitute the emerging army from Khorasan that will eventually liberate the Holy Land. They are the Abdal who will give the Bai’ah to Imam al-Mahdi in Makkah.

I do not wish to identify any party or group within that armed Islamic resistance – hence I no longer use the word Taliban.
