The prominent follower of the companions Wahb Ibn Munabbih said about the khawarij: “By Allah the Khawarij were never a jamaʿah (united body), except that Allah split them up into their worse condition. Nor has anyone of them opened his mouth except that Allah smote him on his neck. Never has the Ummah united under a man from the Khawarij. (Abdus-Salām Ibn Burjiss: Munaasihatul-Imām Wahb Ibn Munabbih)
