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 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 ye help him not, still Allah helped him when those who disbelieve drove him forth, the second of two; when they two were in the cave, when he said unto his comrade: Grieve not. Lo! Allah is with us. Then Allah caused His peace of reassurance to descend upon him and supported him with hosts ye cannot see, and made the word of those who disbelieved the nethermost, while Allah's Word it was that became the uppermost. Allah is Mighty, 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 (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
