I've heard that Shaikh Muqbil , one of the Imams of the Salafis, claimed that Imam Abu Hanifa was a deviant (Naudhubillah).
I found this document on a Salafi website that did not deny this claim. In fact, it was said that he called Imam Abu Hanifa insane.
It's in Arabic, and it is quite long, so I can't quite understand it.
I'd greatly appreciate it if a knowledgeable brother can look into the book, and see what it has to say.
Perhaps the secret beliefs of the Salafis will be revealed in doing so.
