O believers, what is amiss with you, that when it is said to you, 'Go forth in the way of God,' you sink down heavily to the ground? Are you so content with this present life, rather than the world to come? Yet the enjoyment of this present life, compared with the world to come, is a little thing. 38 If you go not forth, He will chastise you with a painful chastisement, and instead of you He will substitute another people; and you will not hurt Him anything, for God is powerful over everything. 39 If you do not succour the Apostle, then [know that God will do so - just as] God succoured him at the time when those who were bent on denying the truth drove him away, [and he was but] one of two: when these two were [hiding] in the cave, [and] the Apostle said to his companion, "Grieve not: verily, God is with us." And thereupon God bestowed upon him from on high His [gift of] inner peace, and brought utterly low the cause of those who were bent on denying the truth, whereas the cause of God remained supreme: for God is almighty, wise. 40 Go forth, light-armed and heavy-armed, and strive with your wealth and your lives in the way of Allah! That is best for you if ye but knew. 41 Were it a gain near at hand, and an easy journey, they would have followed thee; but the distance was too far for them. Still they will swear by God, 'Had we been able, we would have gone out with you,' so destroying their souls; and God knows that they are truly liars. 42
