The Prophet Sallallahu ‘Alaihi Wa Sallam said: "(Armies carrying) black flags will come from Khurasan (Afghanistan). No power will be able to stop them and they will finally reach Jerusalem where they will erect their flags."
(Tirmidhi)
Said son of Al Musayyab reported:
"The Black Banners will come from the East from the children of Al Abbas. Then there will remain whatsoever Allah wishes. Then, small Black Banners will come to fight a man from the children of Abu Sufyaan from the East. They will give their allegiance to the Mahdi."
(Nuaym son of Hammad.)
"Pity poor Taliqan (a region in Afghanistan) that at that place are treasures of Allah, but these are not of gold and silver. There are people who have recognized Allah as they should have. They are the supporters of the Mahdi in the End Times."
(Al-Muttaqi al-Hindi, Al-Burhan fi Alamat al-Mahdi Akhir al-zaman, p.59)
Thawban (R.A) reported that Dear Propet(salallaho alayhay wa sallam) said, “ In your old age three men will be killed . Each of them will be the son of a Khalifah. Then the black banners will come out of the east, *1 and they will slaughter you in a way that no Nation has ever done before.Then Dear Prophet(salallaho alayhay wa sallam) said soemthing that I didn’t remember.Then again Dear Prophet(salallaho alayhay wa sallam) said if you see him give him your allegiance, even if you have to crawl over ice, because he is the Khalifah of Allah, the Mahdi.(2 Reference Ibne Majah Page 300, Also in Ahmad's Musnad, al-Haakim's Mustadrak and others)
