Use resources wisely and carefully during war; Practice moderation and restraint; Shoot at enemies but use weapons sparingly.

On the day of Badr, one of the most important battles in Islamic history, Prophet Muhammad (peace be upon him) gave his companions advice on how to fight. He told them that when they encounter the enemy, they should shoot at them with their arrows but use them sparingly so that they do not waste any of their weapons. This hadith teaches us about being wise and careful with our resources and using them only when necessary. It also shows us that even in times of war, we should still practice moderation and restraint. We should not be wasteful or reckless with our resources as this could lead to unnecessary losses or damage.
