Therefore it is necessary that during that Rajat of the Messenger of Allah (s.a.w.s.) and the Holy Imams (a.s.) the earth should not be devoid of Divine Proof and that the tree of Islam should remain verdant, bearing fruits and leaves from the branches of piety and the earth may shine with the light of its Lord. And there is no problem if he is called as Mahdi as mentioned in traditions.
5- Tafsir Ayyashi: It is narrated from Jabir that he said: I heard Imam Muhammad Baqir (a.s.) say: “By Allah, after the death of Imam Qaim (a.s.) a person from us Ahle Bayt (a.s.) will rule for 309 years.” I asked: When will this be? He replied: After the passing away of Imam Qaim (a.s.). I asked: For how many years will Imam Qaim rule on the earth after reappearance? He replied: Nineteen years from his reappearance to his death. I said: Would there will be a great confusion after that?
He replied: Yes, for fifty years. Then Muntasir will do Rajat and he will kill his enemies and imprison them till people will begin to say that if he had been from the progeny of the prophets, he would not have shed so much blood. And all the people of the world will unite against him and attack him and he will seek refuge in Kaaba. He will have to face severe calamities and he will be killed in this process. After his killing, Saffah will rise up in fury and eliminate all our enemies.
And O Jabir, do you know who Muntasir and Saffah are? Muntasir is Husain bin Ali (a.s.) and Saffah means Ali Ibne Abi Talib (a.s.).” The text of this tradition is present in Tafsir Ayyashi , Vol. 2, Pg. 326.
6- Ghaibat Tusi: A group of scholars has narrated from Bazufari from Ali bin Sinan Musali from Ali bin Husain from Ahmad bin Muhammad bin Khalil from Ja’far bin Ahmad Misri from his uncle Husain bin Ali from his father from Imam Ja’far Sadiq (a.s.) from his respected father from Amirul Momineen (a.s.) from the Messenger of Allah (s.a.w.s.) that he said on the eve of his departure from the world: “O Abul Hasan bring a scroll and pen and ink.” Then he dictated his will and came to the following statement: “O Ali, after me there will be twelve Imams and after them there will be twelve Mahdis and you are the first of them.
Then he named one Imam after another and then said: Then Hasan will entrust this post of Imamate to his son, MHMD, who survives from Aale Muhammad (a.s.) and in this way the twelve will be complete and after that there will be twelve Mahdis.
