Believers, what is the matter with you that when you are asked to go forth in the cause of God, you cling slothfully to the land? Do you prefer the life of this world to the Hereafter? But little is the comfort of this life, compared to that of the Hereafter. 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 Whether lightly or heavily, march on and fight for the Way of Allah, with your wealth and your persons. This will be best for you, if you but knew. 41 Had it been a near advantage and a short journey, they would certainly have followed you, but the tedious journey was too long for them; and they swear by Allah: If we had been able, we would certainly have gone forth with you; they cause their own souls to perish, and Allah knows that they are most surely 42
