O you who believe! What (excuse) have you that when it is said to you: Go forth in Allah's way, you should incline heavily to earth; are you contented with this world's life instead of the hereafter? But the provision of this world's life compared with the hereafter is but little. 38 Unless you go out (to strive), God will inflict grievous punishment on you, and bring other people in your place, and you will not be able to harm Him in the least, for God has the power over all things. 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 Whether lightly or heavily, march on and fight for the Way of Allah, with your wealth and your persons. This will be best for you, if you but knew. 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
