Kitab al-Fitan · Nu'aym ibn Hammad

Twelve Persian kings are attending the great epic, the youngest of whom is a king and the least of whom are soldiers is the ruler of the Romans. Allah Almighty has two treasures in Yemen, one of which he brought on the day of Yarmouk. The Azd at that time were a third of the people, and the other will be brought on the day of the great epic, seventy thousand, with their swords drawn.

The epics were at the hands of a man from the people of Heraclius, the fourth and fifth, who was called Tayyara, and the leader of the people at that time was a man from the Banu Hashim. Seventy thousand people would come to him in Yemen, their swords sharpened.

O community of Qais, love Yemen, and O community of Yemen, love Qais, for it is about to be that no one will be killed for this religion except you. Qais, the knights of the people on the day of epics, and Yemen is the hope of Islam.
