So, in 1750 a Protestant in Ireland couldn’t for the most part murder a Catholic on the street without repercussions? Not sure that’s true.
BTW, under sharia financial compensation is usually an option for any murder.
Kafir’s had to bow as a Muslim passed by on the road in Islamic Sicily or be flogged.
Killing a kafir isn't murder. If the people involved are of equal class it's a murder. If the crime was murder then the accused will be executed under sharia. There was no compensation for murder. There is compensation as one would lose property for killing a kafir.
