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 If ye march not forth, He will torment you with a torment afflictive, and will substitute for you a people - other than you; and Him ye cannot hurt in aught; and Allah is over everything Potent. 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 March forth whether light or heavy, and strive in the way of Allah with your belongings and your lives. That is best for you if you only knew it. 41 Were it a gain near at hand, and an easy journey, they would have followed thee; but the distance was too far for them. Still they will swear by God, 'Had we been able, we would have gone out with you,' so destroying their souls; and God knows that they are truly liars. 42
