Believers, why is it that when you are told to march for the cause of God, you seem to linger at home. Have you given preference to the worldly life over the life hereafter? The worldly gains compared to those of the next life are but very little. 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 him, yet God has helped him already, when the unbelievers drove him forth the second of two, when the two were in the Cave, when he said to his companion, 'Sorrow not; surely God is with us.' Then God sent down on him His Shechina, and confirmed him with legions you did not see; and He made the word of the unbelievers the lowest; and God's word is the uppermost; God is All-mighty, All-wise. 40 Go ye forth, (whether equipped) lightly or heavily, and strive and struggle, with your goods and your persons, in the cause of Allah. That is best for you, if ye (but) knew. 41 Were it a gain at hand or a short journey, they would have surely followed you, but the distance seemed too far to them. Still they will swear by Allah: "If only we could, we would surely have gone forth with you." They merely bring ruin upon themselves. Allah knows well that they are liars. 42
