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 do not march for His cause, He will afflict your with a painful punishment and replace you by another nation and your (destruction) will not harm Him at all. God has power over all things. 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 Whether lightly or heavily, march on and fight for the Way of Allah, with your wealth and your persons. This will be best for you, if you but knew. 41 If there had been immediate gain (in sight), and the journey easy, they would (all) without doubt have followed thee, but the distance was long, (and weighed) on them. They would indeed swear by Allah, "If we only could, we should certainly have come out with you": They would destroy their own souls; for Allah doth know that they are certainly lying. 42
