Are the Terrorists of Today the Khawaarij?1
Question: The questioner asks about this group that has today left the Muslims and opposed them. They carry out bombings and terrorize people who once felt safe. Are these people truly part of the Khawaarij or are they disbelievers?
Answer: This group that has left the Muslims, rebelling against them – this is the result of disassociating oneself from the scholars. I mentioned the consequences of this during the last part of the (previous) lecture. They broke away from the scholars, broke away from the Muslim leaders, and the disbelievers and hypocrites put these ideologies into their heads. So, they’ve become outcasts in Muslim societies.
They are Khawaarij, no doubt. This act of theirs is the act of the Khawaarij. Rather, they’re even more violent and extreme than the (original) Khawaarij. The (past) Khawaarij didn’t use to destroy buildings and residents. The Khawaarij used to show up face-to-face on the battlefield. They used to fight on the battlefield despite what they were upon of ignorance. But they didn’t used to collapse buildings on everyone who’s in them – women, children, the innocent, those at peace with Muslims, people with whom Muslims have a treaty, people guaranteed safety. The Khawaarij used not to do this. This is worse and more violent than the actions of the (original) Khawaarij. This is more like the actions of the Qaraamitah (a severely violent, misguided sect). They’re more like the Qaraamitah because the actions of the Qaraamitah are secret, based on secrecy and underhandedness and what these people today do is also based on secrecy. The (former) Khawaarij – their actions were not kept hidden and secret; they would make themselves and their objectives known, publicly announcing them. So, these people are even worse than Khawaarij.
