Believers! What is amiss with you that when it is said to you: "March forth in the cause of Allah," you cling heavily to the earth? Do you prefer the worldly life to the Hereafter? Know well that all the enjoyment of this world, in comparison with the Hereafter, is trivial. 38 If you do not go forth to war [in God's cause,] He will chastise you with grievous chastisement, and will place another people in your stead - whereas you shall in no wise harm Him: for, God has the power to will anything. 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 you are light (being healthy, young and wealthy) or heavy (being ill, old and poor), strive hard with your wealth and your lives in the Cause of Allah. This is better for you, if you but knew. 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
