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 March forth whether light or heavy, and strive in the way of Allah with your belongings and your lives. That is best for you if you only knew it. 41 Had there been some wealth near at hand or a short journey, they would have certainly accompanied you, but the difficult path became very distant for them; and they will now swear by Allah that “Had we been able, we would have surely accompanied you”; they destroy their own souls; and Allah knows that undoubtedly, they are indeed liars. 42
