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 ۞ Hence, let them fight in God's cause - all who are willing to barter the life of this world for the life to come: for unto him who fights in God's cause, whether he be slain or be victorious, We shall in time grant a mighty reward. 74 And what is wrong with you that you fight not in the Cause of Allah, and for those weak, ill-treated and oppressed among men, women, and children, whose cry is: "Our Lord! Rescue us from this town whose people are oppressors; and raise for us from You one who will protect, and raise for us from You one who will help." 75 The believers fight in the way of God, and the unbelievers fight in the idols' way. Fight you therefore against the friends of Satan; surely the guile of Satan is ever feeble. 76
