SHAFAQNA – It is narrated that Jaber ibn Abdullah Ansari (RA) asked the prophet of Islam (PBUH): Who are your successors after Ali ibn Abitaleb (AS)? The Prophet of Islam (PBUH) replied: Imam Hassan (AS) and Imam Hussain (AS), then Ali ibn Hussain (AS), after him Mohammad ibn Ali (AS), after him Jaffar ibn Mohammad (AS), after him Mosa ibn Jaffar (AS), after him Ali ibn Mosa, after him Mohammad ibn Ali (AS), after him Ali ibn Mohammad (AS), after him Hassan ibn Ali (AS), and after him, Mahdi (AS). He is the one who will spread justice in the world after it has been filled with oppression and cruelty. O’ Jaber, they are Caliphs and my successors from my family; whoever obeys them, obeys me, and whoever disobeys them, disobeys me; whoever denies any of them or all of them, as if I have been denied. It is due to their existence that God has kept this world, and protection and survival of this world will also be for their sake as long as Allah (SWT) wants to do so .
