There are no external saviours, not in the original Jewish scriptures nor in the Quran.
God does not change the condition of a people until they change what is in themselves.
There is only one way to head off what’s coming, and that is do to what the Quran tells us to do: to warn the elite in order to make them eligible for the punishments of God.
That is the Quranic model.
