Quran 8:12 I shall terrorize the infidels. So wound their bodies and incapacitate them because they oppose Allah and His Apostle.
Quran 8:57 If you gain mastery over them in battle, inflict such a defeat as would terrorize them, so that they would learn a lesson and be warned.
Ishaq:326 If you come upon them, deal so forcibly as to terrify those who would follow, that they may be warned. Make a severe example of them by terrorizing Allahs enemies.
Quran 8:67 It is not fitting for any prophet to have prisoners until he has made a great slaughtered in the land.
