O believers, take precautions, and advance in detachments, or go all together 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, 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 ۞ Those who want to buy the life hereafter with this life should fight for the cause of God. We will give them a great reward whether they are killed or whether they are victorious. 74 And how should you not fight for the cause of God, and for the helpless old men, women, and children who say, "Deliver us, Lord, from this city of wrongdoers, grant us a protector out of Your grace and grant us a supporter out of Your grace?" 75 Those who have attained to faith fight in the cause of God, whereas those who are bent on denying the truth fight in the cause of the powers of evil. Fight, then, against those friends of Satan: verily, Satan's guile is weak indeed! 76
