O you who believe! What (excuse) have you that when it is said to you: Go forth in Allah's way, you should incline heavily to earth; are you contented with this world's life instead of the hereafter? But the provision of this world's life compared with the hereafter is but little. 38 If you do not migrate, He will afflict you with a painful punishment and bring other people in your stead and you will not be able to harm Him in the least; and Allah is Able to do 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 O believers, go out in the cause of God, (whether) light or heavy, and strive in the service of God, wealth and soul. This is better for you if you understand. 41 Had it been an easy gain and a moderate trip, the hypocrites would have followed you, but distant to them was the journey. And they will swear by Allah, "If we were able, we would have gone forth with you," destroying themselves [through false oaths], and Allah knows that indeed they are liars. 42
