Believers! What is amiss with you that when it is said to you: "March forth in the cause of Allah," you cling heavily to the earth? Do you prefer the worldly life to the Hereafter? Know well that all the enjoyment of this world, in comparison with the Hereafter, is trivial. 38 If ye go not forth He will afflict you with a painful doom, and will choose instead of you a folk other than you. Ye cannot harm Him at all. Allah is Able to do all things. 39 If you do not help him, Allah will help him as He helped him when he was driven out with one other (Abu Bakr) by the unbelievers. When the two were in the cave, he said to his companion: 'Do not sorrow, Allah is with us' Then Allah caused His tranquility (shechina) to descend upon him and supported him with legions (of angels) you did not see, and He made the word of the unbelievers the lowest, and the Word of Allah is the highest. Allah is Mighty, Wise. 40 Whether lightly or heavily, march on and fight for the Way of Allah, with your wealth and your persons. This will be best for you, if you but 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
