Believers, why is it that when you are told to march for the cause of God, you seem to linger at home. Have you given preference to the worldly life over the life hereafter? The worldly gains compared to those of the next life are but very little. 38 If ye go not forth He will afflict you with a painful doom, and will choose instead of you a folk other than you. Ye cannot harm Him at all. Allah is Able to do all things. 39 If you do not support him [Muhammad], know that God did support him when those who denied the truth expelled him when the two of them were in the cave, he [Muhammad] told his companion, "Do not worry; for God is with us." So God sent His tranquillity down on him and aided him with forces invisible to you and placed the word of those who disbelieved lowest, while God's word remained supreme. God is powerful and wise. 40 Go forth light and heavy, and strive hard in Allah's way with your property and your persons; this is better for you, if you know. 41 Had there been some wealth near at hand or a short journey, they would have certainly accompanied you, but the difficult path became very distant for them; and they will now swear by Allah that “Had we been able, we would have surely accompanied you”; they destroy their own souls; and Allah knows that undoubtedly, they are indeed liars. 42
