Avira,
How does that Netziv contradict the Rambam’s ikrei emunah?
The Ramban holds that only tzadikim are zocheh to hashgacha pratis (Breishis 18:19) even after Avraham. And the Rambam holds that the level of hashagacha fluctuates according to the level the person is on (in the Moreh, don’t remember where).
The Netziv, if anything, ascribes even more hashgacha than the Ramban and the Rambam himself.
