کتاب الفتن · نُعیم بن حماد

A man emerges from the peninsula and tramples on the people, and sheds blood. Then a man emerges from Khorasan after killing his brother from Banu Hashim, called Abdullah. He remains for about forty years. Then he dies and two men from his household named by the same name differ, so it becomes an epic in Aqraqufa, and they appear close to the caliph. Then it becomes a sign among the Banu al-Asfar, and a star with a tail appears, and it disappears from them and does not return to them.

If the Turks and Khazars appear in the peninsula and Azerbaijan, and the Romans in the depths and its outskirts, the Romans will fight a man from Qays, from the people of Qinnasrin, and the Sufyani will fight the people of the East in Iraq, and each side will be occupied with an enemy. If he fights them for forty days and does not come to him, he will extend the favor of the Romans, provided that neither party gives anything to the other.
