He brought drowsiness upon you to give you His reassurance and sent down water from the sky upon you, so that He might thereby purify you and remove Satan's pollution from you, and make your hearts strong and your feet firm. 11 Lo! Thy Sustainer inspired the angels [to convey this His message to the believers]: "I am with you!" [And He commanded the angels:] "And give firmness unto those who have attained to faith [with these words from Me]: 'I shall cast terror into the hearts of those who are bent on denying the truth; strike, then, their necks, [O believers,] and strike off every one of their finger-tips!" 12 This is because they defied Allah and His Messenger. Whoever defies Allah and His Messenger must know that Allah is severe in punishment. 13 This [for you, O enemies of God]! Taste it, then, [and know] that suffering through fire awaits those who deny the truth! 14 O you who believe! When you meet those who disbelieve, in a battle-field, never turn your backs to them. 15 If any do turn his back to them on such a day - unless it be in a stratagem of war, or to retreat to a troop (of his own)- he draws on himself the wrath of Allah, and his abode is Hell,- an evil refuge (indeed)! 16 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. 17 That (is the case); and (know) that Allah (it is) Who maketh weak the plan of 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
