I believe both the Christians and the Muslims had this sort of system actually, hence they would raid each other’s populations for slaves, to avoid upsetting their gods by enslaving the wrong people.
During crusades, Christians did take Muslim slaves from time to time, but prisoners were usually killed or taken for ransom. Christians definitely didn’t have a whole slave workforce like Muslims did. It wasn’t the way most of the Christian world operated. It was generally frowned upon I would assume. Muslims on the other hand had whole slave armies under their command. It was part of daily life.
