There would be no government and no religion in the world except the rulership of the Progeny of Muhammad and the religion of Islam. Since traditions had clearly mentioned that the ninth descendant of Imam Husain (a.s) would destroy all oppression in the world, the Bani Abbas Caliph summoned Imams Ali Naqi and Hasan Askari (a.s) so that he could keep a close surveillance on them since they were the tenth and the eleventh Imams of the Shias.

That is the reason that Ja'far, the Imam’s brother, who was an evildoer and an agent of the caliph, stepped forward to recite the funeral prayer.
