O ye who believe! Be careful of your duty to Allah, and be with the truthful. 119 It did not behove the people of Madinah and the bedouin Arabs around them that they should refrain from accompanying the Messenger of Allah and stay behind and prefer their own security to his. For whenever they suffer from thirst or weariness or hunger in the Way of Allah, and whenever they tread a place which enrages the unbelievers (whenever anything of this comes to pass), a good deed is recorded in their favour. Allah does not cause the work of the doers of good to go to waste. 120 Nor do they spend an expenditure, small or large, or cross a valley but that it is registered for them that Allah may reward them for the best of what they were doing. 121 ۞ And it is not possible for the Muslims that all of them go out; so it should be that a party from each group goes forth in order to gain knowledge in religion, and upon returning they warn their people in the hope that they may avoid. 122
