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 go not forth, He will chastise you with a painful chastisement, and instead of you He will substitute another people; and you will not hurt Him anything, for God is powerful over everything. 39 If you do not succour the Apostle, then [know that God will do so - just as] God succoured him at the time when those who were bent on denying the truth drove him away, [and he was but] one of two: when these two were [hiding] in the cave, [and] the Apostle said to his companion, "Grieve not: verily, God is with us." And thereupon God bestowed upon him from on high His [gift of] inner peace, and brought utterly low the cause of those who were bent on denying the truth, whereas the cause of God remained supreme: for God is almighty, wise. 40 March forth, whether you are light (being healthy, young and wealthy) or heavy (being ill, old and poor), strive hard with your wealth and your lives in the Cause of Allah. This is better for you, if you but knew. 41 Had the gain been immediate or the journey shorter, they (hypocrites) would certainly have followed you, (Muhammad), but it was too far for them. They will swear by God, "Had we had the ability, we would certainly have marched with you." They destroy only themselves and God knows that they are lying. 42
