Believers, what is the matter with you that when you are asked to go forth in the cause of God, you cling slothfully to the land? Do you prefer the life of this world to the Hereafter? But little is the comfort of this life, compared to that of the Hereafter. 38 Unless you go out (to strive), God will inflict grievous punishment on you, and bring other people in your place, and you will not be able to harm Him in the least, for God has the power over all things. 39 If you do not help (the Prophet, remember) God had helped him when the infidels had forced him to leave (and he was) one of two. When both of them were in the cave, he said to his companion: "Do not grieve, for God is with us." Then God sent divine peace on him, and invisible armies for his help, and made the unbelievers' purpose abject. Most exalted is God's word, for God is all-mighty and all-wise. 40 Go forth, whether light or heavy, and strive with your wealth and your lives in the cause of Allah. That is better for you, if you only knew. 41 (O Prophet), had the gain been close at hand, and easy the journey, they would surely have followed you; but hard was the journey and long the going. Even then they swear by God (and say): "If we had the strength we would surely have gone out with you." They are only ruining themselves, for God is aware they lie. 42
