[Remember how it was] when He caused inner calm to enfold you, as an assurance from Him, and sent down upon you water from the skies, so that He might purify you thereby and free you from Satan's unclean whisperings and strengthen your hearts and thus make firm your steps. 11 And when O dear Prophet, your Lord was inspiring the angels that, “I am with you – so make the believers stand firm; I will soon instil fear into the hearts of the disbelievers, so strike above the disbelievers’ necks and hit their each and every bone joint.” 12 This is because they opposed Allah and His Noble Messenger; and whoever opposes Allah and His Noble Messenger – then indeed Allah’s punishment is severe. 13 That is your punishment (from Allah). So taste this punishment, and know that for the unbelievers is the punishment of the Fire. 14 O you who have believed, when you meet those who disbelieve advancing [for battle], do not turn to them your backs [in flight]. 15 (Whoever deserts the believers) will incur the wrath of God and will dwell in hell, a terrible dwelling. 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 That [is so], and [also] that Allah will weaken the plot of the disbelievers. 18 O disbelievers! If you seek a judgement, then this judgement has come to you; and if you desist, it is better for you; and if you return to mischief, We will punish you again; and your populace will not benefit you, however large it may be – and besides this, Allah is with the Muslims. 19
