Children Of Israel Getting Punishment For What They Didn't Know
That’s based on the limitation of our punishment system in this life. If it was possible to take someone’s life multiple time, we would have implemented the punishment accordingly. But as you said, single life – single payment, two lives – double payment. Already there is a distinction between both criminals. Do you think Allah will treat a single murder in the same way as a mass murder in the Hereafter? The justice suggests No. So He also made a distinction between Ahl-e-Kitab and Mushirik. Because they did not commit the same level of crime.
