إِذْ يُوحِي رَبُّكَ إِلَى الْمَلَائِكَةِ أَنِّي مَعَكُمْ فَثَبِّتُوا الَّذِينَ آمَنُوا ۚ سَأُلْقِي فِي قُلُوبِ الَّذِينَ كَفَرُوا الرُّعْبَ فَاضْرِبُوا فَوْقَ الْأَعْنَاقِ وَاضْرِبُوا مِنْهُمْ كُلَّ بَنَانٍ ﴿١٢﴾

Iz yoohee Rabbuka ilal-malaaa'ikati annee ma'akum fathabbitul-lazeena aamanoo; sa-ulqee fee quloobil-lazeena kafarur-ru'ba fadriboo fawqal-a'naaqi wadriboo minhum kulla banaan.

(12) [Remember] when your Lord inspired to the angels, "I am with you, so strengthen those who have believed. I will cast terror into the hearts of those who disbelieved, so strike [them] upon the necks and strike from them every fingertip."
