The khawaarij of old and the contemporary khawaarij–Every people have inheritors and every land has a cultivator
Al-Allaamah Rabee Bin Haadi Al-Madkhali (may Allaah preserve him) stated:
The khawaarij used to oppose Ali, and they used to oppose the sahaabah, (claiming) that they were the ones in compliance (with the teachings) of Islaam; and that the Sahaabah were misguided and had become disbelievers. It is the same at present– as the saying goes, history repeats itself; at present–according to the these khawaarij– the scholars of the Sunnah are misguided, worshipers of the rulers, spies, employees, people of feasts and ambiguity…and ….and… other distorted (or defamatory statements of these khawaarij) by way of which they hinder the youth of the Ummah from the truth and from the path of Allaah (تبارك وتعالى).
