O you who have believed, what is [the matter] with you that, when you are told to go forth in the cause of Allah, you adhere heavily to the earth? Are you satisfied with the life of this world rather than the Hereafter? But what is the enjoyment of worldly life compared to the Hereafter except a [very] little. 38 Unless you go out (to strive), God will inflict grievous punishment on you, and bring other people in your place, and you will not be able to harm Him in the least, for God has the power over all things. 39 If ye help him not, still Allah helped him when those who disbelieve drove him forth, the second of two; when they two were in the cave, when he said unto his comrade: Grieve not. Lo! Allah is with us. Then Allah caused His peace of reassurance to descend upon him and supported him with hosts ye cannot see, and made the word of those who disbelieved the nethermost, while Allah's Word it was that became the uppermost. 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 (O Prophet), had the gain been close at hand, and easy the journey, they would surely have followed you; but hard was the journey and long the going. Even then they swear by God (and say): "If we had the strength we would surely have gone out with you." They are only ruining themselves, for God is aware they lie. 42
