The status of Ameerul Mo'mineen Ali (AS) is the greatest status after the Prophet Muhammad (SAWA), then the status of Fatimah (AS), then the status of Imam Hasan (AS), then Imam Husain (AS) then others Imams. We have narrations that the status of Imam Al-Mahdi (AS) is higher than the eight Imams before him.
No doubt, all the Infallible Imams are from one Noor.
'Wassalam.
