Musnad Abu Ya'la al-Mawsili 121:3

Abu Khaythama narrated to us, Muhammad ibn Mus'ab narrated to us, al-Awza'i narrated to us, from Rabi'ah, from Anas ibn Malik, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "The Dajjal will emerge from the Jewish quarter of Isfahan. With him will be seventy thousand Jews, upon them are the *sijan* (cloaks/garments)."
