کتاب الفتن · نُعیم بن حماد

Al-Sufyani sends his horses and his soldiers, and he reaches the entire east from the land of Khorasan and the land of Persia, and the people of the east revolt against them and fight them, and there will be conflicts between them in different places. If their fight against him lasts for a long time, they pledge allegiance to a man from Banu Hashim, and he is at the end of the east that day. Then he goes out with the people of Khurasan, with a yellow-bearded man from Banu Tamim, a servant of theirs, going out to him with five thousand. The mountains of Rawasi welcomed him to their destination, and he and the horses of the Sufyani met and defeated them and killed many of them, then the Sufyani would gain the upper hand and the Hashemi would flee, and Shuaib bin Saleh would go out in hiding to Bayt al-Maqdis, to provide his home for the Mahdi when he was informed of his departure to the Levant.

Before the Mahdi, a man will emerge from his household in the East. He will carry the sword on his shoulder for eight months. He will be killed, mutilated, and head to Jerusalem. He will not reach it until he dies. The black banners that come from Khorasan will descend on Kufa. When the Mahdi appears in Mecca, he will send the pledge of allegiance to the Mahdi.
