When He caused calm to fall on you as a security from Him and sent down upon you water from the cloud that He might thereby purify you, and take away from you the uncleanness of the Shaitan, and that He might fortify your hearts and steady (your) footsteps thereby. 11 And recall what time thy Lord inspired the angels: verily I am with you, so keep firm those who have believed; I will cast horror into the hearts of those who have disbelieved, so smite them above the neck and smite of them every fingertip. 12 That was because they defied God and His Messenger. He who defies God and His Messenger shall be severely punished by God. 13 That (is the award), so taste it, and (know) that for disbelievers is the torment of the Fire. 14 O you who believe! when you meet those who disbelieve marching for war, then turn not your backs to them. 15 For any one who turns his back on that day, except to manoeuvre or rally to his side, will bring the wrath of God on himself, and have Hell as abode; and what an evil destination! 16 And you did not kill them, but it was Allah who killed them. And you threw not, [O Muhammad], when you threw, but it was Allah who threw that He might test the believers with a good test. Indeed, Allah is Hearing and Knowing. 17 Therefore take this, and (know that) Allah will weaken the scheme of the disbelievers. 18 If you (the pagans) are looking for conquest, you certainly had a great chance (at the battle of Badr). But if you were to give up such a desire, it would be better for you. If you again wage war against Us, We will be ready for such a confrontation. Your man-power will be of no help to you no matter how much you have; God is with the believers. 19
