When He caused calm to fall on you as a security from Him and sent down upon you water from the cloud that He might thereby purify you, and take away from you the uncleanness of the Shaitan, and that He might fortify your hearts and steady (your) footsteps thereby. 11 When your Lord commanded the angels, saying, "I am with you, so make those who believe stand firm. I will instill fear in the hearts of those who deny the truth: so strike their necks and strike all their finger joints!" 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 Thus (will it be said): "Taste ye then of the (punishment): for those who resist Allah, is the penalty of the Fire." 14 O you who believe! when you meet those who disbelieve marching for war, then turn not 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 You did not kill them; it was God who killed them; and when you [Prophet] threw [sand] at them it was not you, but God who threw it so that He might confer on the believers a great favour from Himself. Surely, God is all hearing, all-knowing, 17 This [was God's purpose] - and also [to show] that God renders vain the artful schemes of those who deny the truth. 18 If you (the pagans) are looking for conquest, you certainly had a great chance (at the battle of Badr). But if you were to give up such a desire, it would be better for you. If you again wage war against Us, We will be ready for such a confrontation. Your man-power will be of no help to you no matter how much you have; God is with the believers. 19
