کتاب الفتن · نُعیم بن حماد

I have heard that the black flags emerge from Khurasan, and when they land at the Khorasan obstacle, they land denying Islam, and only the banners of the foreigners from the Maghreb reject them.

Black banners will come from the East, led by men like majestic ships, men of honor, whose lineages are villages, and whose names are nicknames. They will conquer the city of Damascus, and mercy will be spared from them for three hours.
