[Penisvergroesserung]

No offense and I'm just asking a question because of my ignorance. I am assuming that the only thing that separates the two "groups" is the belief in question and therefore Sh. Abdul Salam Rustami is still thoroughly a Hanafi and hadith scholar along the Deobandi undestsanding (being that no other issue was raised other than this) ... Is it really this one secondary aqida issue that people are distinguishing "real" from "fake" Deobandis?
