Say to the remaining behind from the Arabs, (often mistranslated as nomads or Bedouins although this verse clearly explains that they are a nation of city dwellers): "You will be called to a nation (owners) of (a) strong (severe) might/power , you fight/kill them or they submit/surrender, so if you obey, God gives/brings you a good/beautiful, reward , and if you turn away as/like you turned away from before, He tortures you a painful torture."
