O you who have believed, what is [the matter] with you that, when you are told to go forth in the cause of Allah, you adhere heavily to the earth? Are you satisfied with the life of this world rather than the Hereafter? But what is the enjoyment of worldly life compared to the Hereafter except a [very] 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 help him (Muhammad SAW) not (it does not matter), for Allah did indeed help him when the disbelievers drove him out, the second of two, when they (Muhammad SAW and Abu Bakr) were in the cave, and he (SAW) said to his companion (Abu Bakr): "Be not sad (or afraid), surely Allah is with us." Then Allah sent down His Sakinah (calmness, tranquillity, peace, etc.) upon him, and strengthened him with forces (angels) which you saw not, and made the word of those who disbelieved the lowermost, while it was the Word of Allah that became the uppermost, and Allah is All-Mighty, 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 Had the gain been immediate and the journey shorter, they would have followed you: but the distance seemed too great for them. Yet they will swear by God, "Had we been able, we would have gone out with you." They bring ruin upon themselves. God knows that they are surely lying. 42
