Musannaf Ibn Abi Shayba 37:383

Yunus ibn Muhammad narrated to us, from Hammad ibn Salamah, from Ishaq ibn Abdullah ibn Abi Talha, from Anas, that the Messenger of Allah (may Allah bless him and grant him peace) said: "Indeed, the Dajjal will traverse the entire earth except for Makkah and Madinah. He will come to Madinah and find at every one of its mountain passes rows of angels. Then he will come to Sabkhat al-Jurf and pitch his tent. Then Madinah will shake three tremors, and every hypocrite man and hypocrite woman will come out to him."
