Believers, why is it that when it is said to you: 'March in the Way of Allah' you linger with heaviness in the land? Are you content with this life rather than the Everlasting Life? Yet the enjoyment of this life in (comparison to) the Everlasting Life is 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 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 Whether unarmed or well equipped, march and fight for the cause of God with your possessions and in person. This would be better for you, if only you knew it. 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
