O believers, what is amiss with you, that when it is said to you, 'Go forth in the way of God,' you sink down heavily to the ground? Are you so content with this present life, rather than the world to come? Yet the enjoyment of this present life, compared with the world to come, is a little thing. 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 (the Prophet, remember) God had helped him when the infidels had forced him to leave (and he was) one of two. When both of them were in the cave, he said to his companion: "Do not grieve, for God is with us." Then God sent divine peace on him, and invisible armies for his help, and made the unbelievers' purpose abject. Most exalted is God's word, for God is all-mighty and all-wise. 40 Go forth, light-armed and heavy-armed, and strive with your wealth and your lives in the way of Allah! That is best for you if ye but knew. 41 Were there a gear nigh and a journey moderate, they would have surely followed thee, but the distance seemed far unto them. And anon they will be swearing by Allah: if only we could, we would surely have come forth with you. They destroy their own souls; and Allah knoweth that verily they are liars. 42
