The ruling on those who carried out the bombings from among the Khawarij

Question:
The questioner says: Another question, Honorable Shaykh. You mentioned in one of your lessons that those who carried out the bombings are from the Khawarij. How can they be from the Khawarij when they do not declare people disbelievers for committing major sins?

Answer:
Who told you that they do not declare people disbelievers? They did not commit what they committed except because they consider the Muslims to be disbelievers. If they believed that the Muslims were upon Islam, they would not have fought them. They consider them disbelievers, as evidenced by the fact that they committed what they committed. If they believed in their Islam, they would not have killed them. In my view, they are more severe than the Khawarij, because the Khawarij are people of prayer, fasting, and independent legal reasoning. Do any of you see them praying or coming to the mosques?
No. Second, the Khawarij are people of fasting, prayer, and worship. These people have none of these things. They are hidden, and no one knows about them.
Like thieves, they are hidden. Like wolves, they hide to ambush. The Khawarij do not demolish houses or betray people. The Khawarij appear openly and carry weapons openly. The Muslims fight them openly in battle. They do not come to houses to kill the people inside, including the young, the old, women, children, and the sick. They kill the sick in hospitals. The Khawarij did not do such things. So their crime is more severe than that of the Khawarij. Yes.
