H 464 - It is narrated from Ibn Abu Umair from Ibn Bazi from Mansur bin Yunus from Ismail bin Jabir from Abu Khalid Kabuli that Imam Muhammad Baqir (a.s) said
When the Qaim enters Kufa, no believer would remain, but that he would be in Kufa or that he would move to Kufa. It is also mentioned in the discourse of Amirul Momineen (a.s) that Imam Mahdi (a.s) would address his companions: Come and join us to march against this transgressor [Sufyani, Dajjal and every tyrant who confronts the Imam].
