Marmaduke Pickthall, The Meaning of The Glorious Koran. An Explanatory Translation (1930)

8. That He might cause the Truth to triumph and bring vanity to naught, however much the guilty might oppose;

9. When ye sought help of your Lprd and He answered you (saying): I will help you with a thousand of the angels, rank on rank.

10. Allah appointed it only as good tidings, and that your hearts thereby might be at rest. Victory cometh only by the help of Allah. Lo! Allah is Mighty, Wise.

11. When he made the slumber rail upon you as a reassurance from Him and sent down water from the sky upon you, that thereby He might purify you, and remove from you the fear of Satan, and make strong your hearts and firm (your) feet thereby.

12. When thy Lord inspired the angels, (saying:) I am with you. So make those who believe stand firm. I will throw fear into the hearts of those who disbelieve. Then smite the necks and smite of them each finger.

13. That is because they opposed Allah and His messenger. Whoso opposeth Allah and His messenger, (for him) lo! Allah is severe in punishment.

14. That (is the award), so taste it, and (know) that for disbelievers is the torment of the Fire.

15. O ye who believe! When ye meet those who disbelieve in battle, turn not your backs to them.

16. Whoso on that day turneth his back to them, unless manoeuvring for battle or intent to join a company, he truly hath incurred wrath from Allah, and his habitation will be hell, a hapless journey’s-end.

17. Ye (Muslims) slew them not, but Allah slew them. And thou (Muhammad) threwest not when thou didst throw, but Allah threw, that He might test the believers by a fair test from Him. Lo! Allah is Hearer, Knower.
