What follows is a refutation of a doubt used to defend the Kharijites, those who do not declare Muslims to be disbelievers on account of major sins such as drinking, fornicating, gambling, leaving the obligations and what is like that. The Kharijites are many factions, however all of them are united upon one major sin on account of which they declare others to be disbelievers (without tafseel) and that is not ruling by other than what Allaah revealed.
