O you who believe! What is the matter with you, that when you are asked to march forth in the Cause of Allah (i.e. Jihad) you cling heavily to the earth? Are you pleased with the life of this world rather than the Hereafter? But little is the enjoyment of the life of this world as compared with the Hereafter. 38 If you do not go forth to war [in God's cause,] He will chastise you with grievous chastisement, and will place another people in your stead - whereas you shall in no wise harm Him: for, God has the power to will anything. 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 forth, whether lightly or heavily equipped, and strive and struggle, with your goods and your persons, for the cause of God. That is better for you, if you only knew. 41 Had there been [a prospect of] immediate gain, and an easy journey, they would certainly have followed thee, [O Prophet:] but the distance was too great for them. And yet, [after your return, O believers,] they will swear by God, "Had we been able to do so, we would certainly have set out with you!" - [and by thus falsely swearing] they will be destroying their own selves: for God knows indeed that they are lying! 42
