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, He will punish you with a painful punishment and will replace you with another people, and you will not harm Him at all. And Allah is over all things competent. 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, light-armed and heavy-armed, and strive with your wealth and your lives in the way of Allah! That is best for you if ye but knew. 41 Were it a gain at hand or a short journey, they would have surely followed you, but the distance seemed too far to them. Still they will swear by Allah: "If only we could, we would surely have gone forth with you." They merely bring ruin upon themselves. Allah knows well that they are liars. 42
