36 Surely the number of months with Allāh is twelve months by Allāh’s ordinance, since the day when He created the heavens and the earth — of these four are sacred. That is the right religion; so wrong not yourselves therein. And fight the polytheists all together as they fight you all together. And know that Allāh is with those who keep their duty.

37 Postponing (of the sacred month) is only an addition in disbelief, whereby those who disbelieve are led astray. They allow it one year and forbid it (another) year, that they may agree in the number (of months) which Allāh has made sacred, and thus make lawful what Allāh has forbidden. The evil of their doings is made fair-seeming to them. And Allāh guides not the disbelieving people.

38 O you who believe, what (excuse) have you that when it is said to you, Go forth in Allāh’s way, you should incline heavily to earth? Are you contented with this world’s life instead of the Hereafter? The provision of this world’s life is but little as compared with the Hereafter.

39 If you go not forth, He will chastise you with a painful chastisement, and bring in your place a people other than you, and you can do Him no harm. And Allāh is Possessor of power over all things.

40 If you help him not, Allāh certainly helped him when those who disbelieved expelled him — he being the second of the two; when they were both in the cave, when he said to his companion: Grieve not, surely Allāh is with us. So Allāh sent down His tranquillity on him and strengthened him with hosts which you saw not, and made lowest the word of those who disbelieved. And the word of Allāh, that is the uppermost. And Allāh is Mighty, Wise.

41 Go forth, light and heavy, and strive hard in Allāh’s way with your wealth and your lives. This is better for you, if you know.

42 Had it been a near gain and a short journey, they would certainly have followed thee, but the hard journey was too long for them. And they will swear by Allāh: If we had been able, we would have gone forth with you. They cause their own souls to perish; and Allāh knows that they are liars.
