Believers! Always be on your guard against encounters. Then (as circumstance demands) either advance in detachments or advance in a body. 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 a bounty (victory and booty) comes to you from Allah, he would surely say - as if there had never been ties of affection between you and him - "Oh! I wish I had been with them; then I would have achieved a great success (a good share of booty)." 73 ۞ Let them wherefore fight in the way of Allah those who have purchased the life of this world for the Hereafter. And whosoever fighteth in the way of Allah, and is then slain or overcometh, We shall vouchsafe unto him a mighty hire. 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 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
