Believers, why is it that when you are told to march for the cause of God, you seem to linger at home. Have you given preference to the worldly life over the life hereafter? The worldly gains compared to those of the next life are but very little. 38 If you do not march for His cause, He will afflict your with a painful punishment and replace you by another nation and your (destruction) will not harm Him at all. God has power over all things. 39 If you will not aid him, Allah certainly aided him when those who disbelieved expelled him, he being the second of the two, when they were both in the cave, when he said to his companion: Grieve not, surely Allah is with us. So Allah sent down His tranquillity upon him and strengthened him with hosts which you did not see, and made lowest the word of those who disbelieved; and the word of Allah, that is the highest; and Allah is Mighty, Wise. 40 Migrate – whether willingly or with a heavy heart and fight in Allah's cause with your wealth and your lives; this is better for you, if you realise. 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
