[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."1
Translation: Saheeh International (English)
1 By which they grasp and manipulate their weapons. Also interpreted as "all extremities," i.e., their hands and feet.
Remember O Prophet when Allah inspired the angels, who He reinforced the believers with in the Battle of Badr, telling the angels: I am with you. aiding you with help and support, so strengthen the determination of the believers in fighting their enemy. I will cast great fear into the hearts of those who disbelieve. Strike then the necks of the disbelievers to kill them and hit their joints and limbs to hinder them from fighting.
