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 march not forth, He will punish you with a painful torment and will replace you by another people, and you cannot harm Him at all, and Allah is Able to do all things. 39 If you do not succour the Apostle, then [know that God will do so - just as] God succoured him at the time when those who were bent on denying the truth drove him away, [and he was but] one of two: when these two were [hiding] in the cave, [and] the Apostle said to his companion, "Grieve not: verily, God is with us." And thereupon God bestowed upon him from on high His [gift of] inner peace, and brought utterly low the cause of those who were bent on denying the truth, whereas the cause of God remained supreme: for God is almighty, 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 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
