Have you not considered the chiefs of the children of Israel after Musa, when they said to a prophet of theirs: Raise up for us a king, (that) we may fight in the way of Allah. He said: May it not be that you would not fight if fighting is ordained for you? They said: And what reason have we that we should not fight in the way of Allah, and we have indeed been compelled to abandon our homes and our children. But when fighting was ordained for them, they turned back, except a few of them, and Allah knows the unjust.

Have you not seen those to whom it was said: Withhold your hands, and keep up prayer and pay the poor-rate; but when fighting is prescribed for them, lo! a party of them fear men as they ought to have feared Allah, or (even) with a greater fear, and say: Our Lord! why hast Thou ordained fighting for us? Wherefore didst Thou not grant us a delay to a near end? Say: The provision of this world is short, and the hereafter is better for him who guards (against evil); and you shall not be wronged the husk of a date stone.

Surely the number of months with Allah is twelve months in Allah's ordinance since the day when He created the heavens and the earth, of these four being sacred; that is the right reckoning; therefore be not unjust to yourselves regarding them, and fight the polytheists all together as they fight you all together; and know that Allah is with those who guard (against evil).
