The slumber that overcame you was from God that brought you peace. He showered water from the sky over you to clean you, remove satanic wickedness from you, strengthen your hearts, and grant you steadfastness. 11 When your Lord revealed to the angels: I am with you, therefore make firm those who believe. I will cast terror into the hearts of those who disbelieve. Therefore strike off their heads and strike off every fingertip of them. 12 That is because they opposed Allah and His Messenger. And whoever opposes Allah and His Messenger - indeed, Allah is severe in penalty. 13 That is your punishment (from Allah). So taste this punishment, and know that for the unbelievers is the punishment of the Fire. 14 Believers, whenever you encounter a hostile force of unbelievers, do not turn your backs to them in flight. 15 And whoever turns his back to them on such a day, unless swerving [as a strategy] for war or joining [another] company, has certainly returned with anger [upon him] from Allah, and his refuge is Hell - and wretched is the destination. 16 You killed them not, but Allah killed them. And you (Muhammad SAW) threw not when you did throw but Allah threw, that He might test the believers by a fair trial from Him. Verily, Allah is All-Hearer, All-Knower. 17 Thus! And know that Allah weakeneth the contrivance of infidels. 18 If you were seeking a judgement, a judgement has now come to you. If you desist, it will be the better for you. But if you return [to hostility] We too will return. And your host will avail you naught, however numerous it may be, and [know] that surely God is with the believers. 19
