Musannaf Ibn Abi Shayba 27:790

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