Shaykh Rabee Ibn Haadi al-Madkhalee (may Allaah preserve him) said in his description of the Haddaadis:
I have clearly stated many times that the one who abandons actions (in totality) is a disbeliever. However, al-Haddaadiyyah have a evil principle with them. It is that when they have connected to a person that which he is free of and he declares openly his dis-association from it, they continue to remain upon accusing that oppressed person with that which they connected to him. So they by way of this evil principle have surpassed the khawaarij.
