﴿ إِذْ يُوحِى رَبُّكَ إِلَى ٱلْمَلَٰٓئِكَةِ أَنِّى مَعَكُمْ فَثَبِّتُوا۟ ٱلَّذِينَ ءَامَنُوا۟ ۚ سَأُلْقِى فِى قُلُوبِ ٱلَّذِينَ كَفَرُوا۟ ٱلرُّعْبَ فَٱضْرِبُوا۟ فَوْقَ ٱلْأَعْنَاقِ وَٱضْرِبُوا۟ مِنْهُمْ كُلَّ بَنَانٍۢ ﴾
“Lo! Thy Sustainer inspired the angels [to convey this His message to the believers]: "I am with you!" [And He commanded the angels:] "And, give firmness unto those who have attained to faith [with these words from Me]: `I shall cast terror into the hearts of those who are bent on denying the truth; strike, then, their necks, [O believers,] and strike off every one of their finger-tips!"”
(When your Lord inspired the angels) it is also said that this means: when your Lord commanded the angels, ((saying:) I am with you) I will help you. (So make those who believe stand firm) in war; it is also said that this means: give those who believe the good news of victory. (I will throw) cast (fear into the hearts of those who disbelieve) the fear of Muhammad (pbuh) and his Companions. (Then smite the necks) their heads (and smite of them each finger) each shaped finger.
