O ye who believe! What aileth you that when it is said unto you: Go forth in the way of Allah, ye are bowed down to the ground with heaviness. Take ye pleasure in the life of the world rather than in the Hereafter? The comfort of the life of the world is but little in the Hereafter. 38 If you do not go forth, He will punish you with a painful punishment and will replace you with another people, and you will not harm Him at all. And Allah is over all things competent. 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 the gain been immediate or the journey easy, they would have followed you; but the distance seemed far to them. Yet they will swear by Allah: 'Had we been able, we would have gone out with you' They bring destruction upon their souls. Allah knows that they are lying. 42
