Believers! Always be on your guard against encounters. Then (as circumstance demands) either advance in detachments or advance in a body. 71 Among you are some who lag behind and if you encounter a setback, they say, "God has been gracious to me; I was not present with them." 72 But, if the Bounty of Allah reaches you, he would surely say as if there had never been any affection between you and him: 'Would that I had been with them! I should have indeed won a great triumph' 73 ۞ Those who barter the life of this world for the next should fight in the way of God. And We shall bestow on him who fights in the way of God, whether he is killed or is victorious, a glorious reward. 74 And what is the matter with you, that you should not fight in Allah’s cause and for the feeble men, and women, and children, who invoke, “Our Lord! Liberate us from this town, the people of which are unjust; and give us a protector from Yourself; and give us a supporter from Yourself.” (Allah has created many supporters for the believers.) 75 Those who believe fight in the cause of Allah, and those who reject Faith Fight in the cause of Evil: So fight ye against the friends of Satan: feeble indeed is the cunning of Satan. 76
