Ghaibat Tusi: The venerable Shaykh, Muhammad bin Hasan Tusi writes inhis Ghaibat:
“A group of scholars has narrated from Harun bin Musa Talakbari and he has narrated from Ahmad bin Ali Razi that he said that once a venerable man in Rayy came to Abul Husain Muhammad bin Ja’far Asadi (a representative of Imam Zaman) and narrated two incidents in connection with Imam Zaman (a.s.) and I also heard them and I think that this occurred before the year 300 A.H. approximately.
An elderly man narrated from Ali bin Ibrahim Fadki that Oodi said:
“I was performing the Tawaf of the Kaaba. I had completed six roundsand was starting on the seventh when I saw a young man on the right side ofthe Kaaba and fragrance was coming from him. His awe had affected thepeople and they had surrounded him so that they may speak to him. I have not heard anyone speak in a more pleasant way nor seen anyone with a better demeanor. I also went there so that I may also get a chance to speak to him, but the crowd pushed me back. I asked the people who he was. People said he is son of Allah’s Messenger, who comes here for one day every year to meet his special followers and speak to them. I called out: My chief, I also want to speak to you so that you may guide me. When he heard this he threw some pebbles towards me which I picked up. People asked: What did he throw towards you? I said: Pebbles. And I opened my fist but saw that they were pieces of gold. I began to follow him till I joined him. He said: Now my proof is complete on you, the truth has become manifest and your blindness is gone. Do you know who I am? I said: No, by Allah.
He said: I am the same Mahdi. I am the Qaim who would fill the earthwith justice and equity as it would be fraught with injustice and tyranny.Know that the earth is never without Divine Proof. And people cannot remainon nature for more than the period Bani Israel remained in the Tiyah desert(forty years). The time of my reappearance has arrived. What I have said is atrust with you, which you must convey to your Shia brothers.”
This traditional report is also mentioned in the Kharaij of Fadaki and inIkmaaluddin narrated from Taliqani quoting from Ali bin Ahmad Khadiji Kufi from Azdi
