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 If you do not go forth, He will chastise you with a painful chastisement and bring in your place a people other than you, and you will do Him no harm; and Allah has power over all things. 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 Go forth, whether light or heavy, and strive with your wealth and your lives in the cause of Allah. That is better for you, if you only 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
