Kitāb al-Ghayba

(66) Ahmad bin Muhammad bin Sa’eed narrated from the previous four narrators from al-Hasan bin Mahboob from al-Ala’ bin Razeen from Muhammad bin Muslim that Abu Ja’far al-Baqir (as) had said: “Expect the cry to come to you surprisingly from the direction of Damascus. Then great deliverance will come to you.”
