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 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 him, (Muhammad), God has already helped him. When the unbelievers expelled him and he was one of the two people in the cave telling his friend, "Do not worry; God is with us," then God gave him confidence and supported him with an army which you did not see and He defeated the cause of the disbelievers and made His own cause stand supreme. God is Majestic and All-wise. 40 March forth light and heavy and strive hard with your riches and your lives in the way of Allah; that is the best for you, if ye have knowledge. 41 Had the gain been immediate or the journey easy, they would have followed you; but the distance seemed far to them. Yet they will swear by Allah: 'Had we been able, we would have gone out with you' They bring destruction upon their souls. Allah knows that they are lying. 42
