Believers! Always be on your guard against encounters. Then (as circumstance demands) either advance in detachments or advance 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 a bounty from God visits you, he will surely say, as if there had never been any affection between you and him, 'Would that I had been with them, to attain a mighty triumph!' 73 ۞ Let those fight in the cause of Allah Who sell the life of this world for the hereafter. To him who fighteth in the cause of Allah,- whether he is slain or gets victory - Soon shall We give him a reward of great (value). 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 The believers fight for the cause of God. The unbelievers fight for the cause of the Satan. So fight against the friends of Satan for the evil plans of Satan are certainly weak. 76
