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.

And it does not beseem the believers that they should go forth all together; why should not then a company from every party from among them go forth that they may apply themselves to obtain understanding in religion, and that they may warn their people when they come back to them that they may be cautious?
