{ I shall cast terror into the hearts of those who have disbelieved, so strike over the necks and strike off all their fingertips } Al-anfal 12

{ Over the necks } : He means the uppermost part of the necks, the part where slaughterings are made, since there are joints there; a blow there separates the head and sends it flying. It is said: He means the head, as it is over the neck.
