It was not for the people of Madinah and for those around them of the Bedouins to stay behind abandoning the Messenger of Allah, nor to prefer their own lives to his life. That is because whatever thirst or fatigue or hunger strikes them in the way of Allah, and whenever they step into a place which infuriates the infidels, and whenever they make a gain from an enemy, a virtuous deed is credited to their account. Surely, Allah does not destroy the reward of the virtuous.
