Musannaf Ibn Abi Shayba 37:504

Yazid ibn Harun narrated to us, he said: Imran ibn Hudayr informed us, from al-Sumayt ibn Umayr, from Ka’b, who said: It is as if I see the vanguard of the one-eyed Dajjal consisting of six hundred thousand Arabs wearing *al-sijan* (cloaks/garments). And he added to me, as a confirmation of what I see: "I see them [the people] being carried away from it."
