"Anyone who denies or claims the permissibility of departing from the Sunnah and uses the Qur'an as the only source of legislation has gone far astray, accordingly, they are guilty of major Kufr (disbelief that takes the Muslim out of Islam) and have apostatized from Islam. That is because in doing so they are belying Allah (Exalted be He) and His Messenger (peace be upon him), denying their commands, and rejecting a great principle of Islam, which Allah has commanded Muslims to resort to, rely upon and follow."
