When He was causing slumber to overcome you as a security from Him, and sending down on you water from heaven, to purify you thereby, and to put away from you the defilement of Satan, and to strengthen your hearts, and to confirm your feet. 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 This, because they have cut themselves off from God and His Apostle: and as for him who cuts himself off from God and His Apostle - verily, God is severe in retribution. 13 For you is this (punishment) to taste, for the infidels the torment of Hell. 14 O YOU who have attained to faith! When you meet in battle those who are bent on denying the truth, advancing in great force, do not turn your backs on them: 15 Whoso turns his back that day to them, unless withdrawing to fight again or removing to join another host, he is laden with the burden of God's anger, and his refuge is Gehenna -- an evil homecoming! 16 And yet, [O believers,] it was not you who slew the enemy, but it was God who slew them; and it was not thou who cast [terror into them, O Prophet,] when thou didst cast it, but it was God who cast it: and [He did all this] in order that He might test the believers by a goodly test of His Own ordaining. Verily, God is all-hearing, all-knowing! 17 That (is the case); and (know) that Allah (it is) Who maketh weak the plan of disbelievers. 18 If you demanded a judgment, the judgment has then indeed come to you; and if you desist, it will be better for you; and if you turn back (to fight), We (too) shall turn back, and your forces shall avail you nothing, though they may be many, and (know) that Allah is with the believers. 19
