O Ye who believe! what aileth you that when it is said unto you: march forth in the way of Allah, ye are weighed down earthward? Are ye pleased with the life of the world rather than the Hereafter? whereas the enjoyment of the life of the world by the side of the Hereafter is but 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 you do not aid the Prophet - Allah has already aided him when those who disbelieved had driven him out [of Makkah] as one of two, when they were in the cave and he said to his companion, "Do not grieve; indeed Allah is with us." And Allah sent down his tranquillity upon him and supported him with angels you did not see and made the word of those who disbelieved the lowest, while the word of Allah - that is the highest. And Allah is Exalted in Might and Wise. 40 O believers, go out in the cause of God, (whether) light or heavy, and strive in the service of God, wealth and soul. This is better for you if you understand. 41 Had it been a near adventure and an easy journey they had followed thee, but the distance seemed too far for them. Yet will they swear by Allah (saying): If we had been able we would surely have set out with you. They destroy their souls, and Allah knoweth that they verily are liars. 42
