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 success comes to you from God he will say, as though no love existed between you and him: "I wish I were with them, for I would have certainly met with great success." 73 ۞ Let those who seek the life of the Next World in exchange for the life of this world fight in the way of Allah. We shall grant a mighty reward to whoever fights in the way of Allah, whether he is slain or comes out victorious. 74 And what reason have you that you should not fight in the way of Allah and of the weak among the men and the women and the children, (of) those who say: Our Lord! cause us to go forth from this town, whose people are oppressors, and give us from Thee a guardian and give us from Thee a helper. 75 These who believe fight in the way of Allah and those who disbelieve fight in the way of the devil. Fight then against the friends of Satan; verily the craft of Satan is ever feeble. 76
