O YOU who have attained to faith! What is amiss with you that, when you are called upon, "Go forth to war in God's cause," you cling heavily to the earth? Would you content yourselves with [the comforts of] this worldly life in preference to [the good of] the life to come? But the enjoyment of life in this world is but a paltry thing when compared with the life to come! 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, 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 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 Had the gain been immediate and the journey shorter, they would have followed you: but the distance seemed too great for them. Yet they will swear by God, "Had we been able, we would have gone out with you." They bring ruin upon themselves. God knows that they are surely lying. 42
