It was not for people of Madina, and the desert arabs around them, to remain behind the Messenger of Allah nor to prefer themselves to him. That is because no thirst or weariness or hunger will afflict them in the Way of Allah, nor will they take a single step to infuriate the kafirun, nor secure any gain from the enemy, without a right action being written down for them because of it. Allah does not let the wage of the good-doers go to waste.
