If a man (or women) is punished to death for some cardinal sin dictated to such punishment under sharia law, upon his death, in his afterlife will the soul be granted heaven exclusively? I think it should be as such since the person already punished on earth using God's Law. Else, the soul will be punished twice, isn't?
How if another person did the same cardinal sin but didn't get caught and lived all his life before died on natural causes?
How these two souls will be treated in afterlife? How Qur'an or Hadith dictates events for these situations?
