Shaykh Khalid Abdul Rahman Al-Misree said, “Firstly (before discussing if ISIS are khawarij or not because some claim they do not make takfeer upon major sins, know) it is upon the Muslims to return their affairs to the ones who are capable.
Allaah, the Most High, stated: “And when there comes to them information about [public] security or fear, they spread it around. But if they had referred it back to the Messenger or to those of authority among them, then the ones who [can] draw correct conclusions from it would have known about it. And if not for the favor of Allah upon you and His mercy, you would have followed Satan, except for a few.” (an-Nisaa: 83)
So if there comes to the Muslim tribulation, and there comes to him an affair of security or fear, then we return back to the Scholars.
Imaam Al-Fawzaan, the ‘Allaamah, the Faqeeh, Al-Fawzaan and other than him from the Scholars, what do they say concerning this group ISIS? They consider them to be Khawaarij and people of Fitnah, and wicked people.
They slaughter the Muslims and they believe that whom so ever does not accept the leadership of their leader, Abu Bakr Al-Baghdaadee, then he is a kaafir.
So how can you say, ‘They (some Muslims) say ISIS do not make takfeer on the basis of a major sin?’ Anyone who does not accept the leadership of this Baghdaadee is an unbeliever according to ISIS. They declare the rulers to be unbelievers. They declare all of the rulers, from the furthest ends of the earth to the nearest to bekuffaar – this is the doctrine of ISIS. They make permissible the spilling of blood, and the slaughter people, and they do not consider anyone a believer except one who accepts them.
So if they are not Khawaarij, who then are the Khawaarij?! They say whoever does not see that allegiance (bai’ah) is to be given to their leader, Baghdaadee, then he is a kaafir (an unbeliever) who must be killed, and all of the rulers of the Muslims are unbelievers. And if this is not the very root and origin of the Khawaarij – then I do not know a khaarijee upon the face of the earth!
For this reason, upon you is to stick to the People of Knowledge, the Scholars, and especially the youth. Upon the youth is to seek knowledge so that they are not taken and led by emotions. As for that which is apparent to us of establishment of the Prescribed Punishments and veneration of the Sharee’ah with ISIS, then that affair is well-known from the Khawaarij. The Prophet (salallaahu ‘alaihi wassallam) stated, as reported by al-Bukhaaree and Muslim:
“You will consider your Prayer insignificant compared to their Prayer, likewise your Fasting compared to their Fasting.”
So they make apparent their veneration of the Sharee’ah with respect to the Salaah, the Zakaah, and the establishment of the Prescribed Punishments (the Hudood), yet they are upon a false and corrupt belief.
For this reason it is necessary that one is not deceived by what they display of veneration of the Sharee’ah. The first of the Khawaarij: For what reason were they fought against by the Companions of the Prophet (salallaahu ‘alaihi wassallam), whilst they announced their veneration of the Sharee’ah – they said: “There is no judgement but the Judgement of Allaah.” So leader of the believers and Companion, ‘Alee (radiyallaahu ‘anhu) said:
“A word of truth by which they intend falsehood.”
So they made apparent veneration of the Sharee’ah and establishing the Prescribed Punishments of the Sharee’ah, yet they made permissible the spilling of the blood of the Companions (radiyallaahu ‘anhum). They declared the Companions of the Prophet to be unbelievers, and they killed them. They made permissible the spilling of their blood in the name of the veneration of the Sharee’ah saying, “There is no judgement but for Allaah,” yet ‘Alee (radiyallaahu ‘anhu) said: “A word of truth by which they intend falsehood.”
So this is the path of the Khawaarij from olden times, so it is obligatory to beware and to take note of this – and to be ardent upon (seeking) knowledge and have a connection to the Scholars and Jurists of the Sunnah and Hadeeth, the Jurists (Fuqahaa), the People of Hadeeth and Athar (Narrations), so that a person does not fall into the traps of these Dajjaals (liars and falsifiers of the truth).”
