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 It will matter little if you do not help the Prophet, for Allah surely helped him when the unbelievers drove him out of his home and he was but one of the two when they were in the cave, and when he said to his companion: "Do not grieve. Allah is with us." Then Allah caused His tranquillity to descend upon him, and supported him with hosts you did not see, He humbled the word of the unbelievers. As for Allah's Word, it is inherently uppermost. Allah is All-Powerful, All-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 (O Prophet), had the gain been close at hand, and easy the journey, they would surely have followed you; but hard was the journey and long the going. Even then they swear by God (and say): "If we had the strength we would surely have gone out with you." They are only ruining themselves, for God is aware they lie. 42
