Musannaf Ibn Abi Shayba 37:407

Zayd ibn al-Hubab narrated to us, he said: Hammad ibn Salamah informed us, from Ali ibn Zayd ibn Jud'an, from al-Hasan, he said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "The Dajjal will wade through the seas up to his knees, and he will reach the clouds, and he will outpace the sun to its setting place. On his forehead is a horn from which snakes emerge. All weapons have been depicted on his body, until he mentioned the sword, the spear, and the *daraq*." He (the narrator) said: I said, "And what is the *daraq*?" He said, "The shield."
