O you who believe! What (excuse) have you that when it is said to you: Go forth in Allah's way, you should incline heavily to earth; are you contented with this world's life instead of the hereafter? But the provision of this world's life compared with the hereafter is but little. 38 Unless ye go forth, He will punish you with a grievous penalty, and put others in your place; but Him ye would not harm in the least. For Allah hath power over all things. 39 It will matter little if you do not help the Prophet, for Allah surely helped him when the unbelievers drove him out of his home and he was but one of the two when they were in the cave, and when he said to his companion: "Do not grieve. Allah is with us." Then Allah caused His tranquillity to descend upon him, and supported him with hosts you did not see, He humbled the word of the unbelievers. As for Allah's Word, it is inherently uppermost. Allah is All-Powerful, All-Wise. 40 Go forth, light and heavy! Struggle in God's way with your possessions and your selves; that is better for you, did you know. 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
