Musannaf Ibn Abi Shayba 37:366

Al-Hasan ibn Musa narrated to us, he said: Shayban narrated to us, from Yahya, from al-Hadrami ibn Lahiq, from Abu Salih, from Aisha, the Mother of the Believers, who said: The Prophet, may Allah bless him and grant him peace, entered upon me while I was weeping. He said: "What makes you weep?" I said: "O Messenger of Allah, I remembered the Dajjal." He said: "Do not weep, for if he emerges while I am alive, I will suffice you against him, and if I die, then your Lord is not one-eyed. He will emerge with the Jews of Isfahan, and he will travel until he descends at the outskirts of Medina. It will have seven gates on that day, with two angels at every gate. The evil ones of its people will go out to him. Then he will proceed until he comes to Ludd. Then Isa ibn Maryam will descend and kill him. Then Isa will remain on the earth for forty years, or close to forty years, as a just leader and a fair judge."
