Shaykh Al-Fawzaan said, “This [claiming it is permissible to kill Muslim police officers in the Muslim lands as they work for apostate governments and leaders] is from the methodology of the Khawarij.
The Khawarij were the same ones who killed Ali Ibn Abi Talib the best companion after Abu Bakr, Umar, and Uthman.
So, those who have the audacity to kill Ali Ibn Abi Talib, would they not then kill
This is exactly from the Khawarij methodology [to make takfeer of Muslim governments and Muslim rulers (i.e. to declare them all to be disbelievers) due to the errors they have which do not necessitate they hAve become disbelievers. Then claim based on their takfeer of them that it is permissible to kill the police who work for them as they themselves have apostated due to working for and supporting apostate rulers and governments].
As for the one who issues for them a fatwa allowing this [killing Muslim police in the Muslim lands], then he’s just like them and one of them.
We seek safety from Allah [from the evil methodology and actions of these people].”
