Musnad Ahmad 30:1333

Husayn ibn Muhammad narrated to us, Jarir—meaning Ibn Hazim—narrated to us, from Muhammad—meaning Ibn Ishaq—from Muhammad ibn Ibrahim al-Taymi, from Abu Salamah, from Abu Hurayrah, who said: I heard the Messenger of Allah, peace and blessings of Allah be upon him, say: "The Dajjal shall certainly descend upon Khuz and Kerman with seventy thousand [people], whose faces are like hammered shields."
