O People who Believe! Be cautious, then advance towards the enemy in small numbers or all together. 71 And behold, there are indeed among you such as would lag behind, and then, if calamity befalls you, say: "God has bestowed His favour upon me in that I did not accompany them." 72 But if, by God's grace, good fortune should be your lot, they will say, "If only I had been with them I should have achieved a great success," as if no affection had existed between you and them. 73 ۞ Let those (believers) who sell the life of this world for the Hereafter fight in the Cause of Allah, and whoso fights in the Cause of Allah, and is killed or gets victory, We shall bestow on him a great 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
