O you who believe! What is the matter with you, that when you are asked to march forth in the Cause of Allah (i.e. Jihad) you cling heavily to the earth? Are you pleased with the life of this world rather than the Hereafter? But little is the enjoyment of the life of this world as compared with the Hereafter. 38 If you do not march for His cause, He will afflict your with a painful punishment and replace you by another nation and your (destruction) will not harm Him at all. God has 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 Had the gain been immediate and the journey shorter, they would have followed you: but the distance seemed too great for them. Yet they will swear by God, "Had we been able, we would have gone out with you." They bring ruin upon themselves. God knows that they are surely lying. 42
