Who is Elia in the bible ? Is it Imam Ali (as) ?

This shia scholar says its Imam Ali (as). He is wrong. The Ahle Sunnah concludes its Prophet Ilyas (as), and the Jews here were looking for him here. Prophet Ilyas (as) is believed to be still alive in both shia and sunni sources, and this is why the Jews were looking for him.

Now just because I am in a disagreement here it doesn't mean I am denying the merits of Imam Ali (as). In fact in the sunni book Hazrat Qadhi Ayyadh Maliki says in his famous book "as-shifa" that:
Rasul Allah(s) said that on Mi'raj He(Sallallaho alaihi wa aalihi wassallam) saw written on the Arsh 'There is no God but Allah, Muhammad is the Messenger of Allah, I(swt) helped Him(S) with Ali(A).

We don't need to rely on speculations when it comes to Imam Ali (as) merits. Imam Ali (as) in reality has uncountable merits.
