The Difference Between Fighting Disbelievers and Killing Protected Non-Muslims

Question:
Among the doubts that some people choose to follow the words of this group, may Allah guide them, is the claim that the Khawarij throughout history were in confrontation and combat with the Muslim authorities, engaging in fighting and deeming the blood of Muslims lawful to shed. As for this group, they say that we are in confrontation and combat with the heads of disbelief, namely the Christians and the Jews, and those who ally with and support them.

Answer:
They are killing them now in Riyadh. Are they Jews and Christians, or are they Muslims? Those who are now bombing the houses, mosques, and offices—are they Muslims, or are they Jews and Christians? They are killing Muslims, and they are also killing the musta'min (non-Muslims granted safe conduct) among the disbelievers. We have musta'min who have a covenant, and it is not permissible to kill them in fulfillment of the covenant between them and the Muslims. Is this not fighting the disbelievers? Killing a protected disbeliever is not fighting the disbelievers; rather, it is a betrayal of Islam and a betrayal of the dhimmah (protection) of the Muslims. Yes.
