Be wise and resourceful in times of need; Be generous with your charity money even if it means sacrificing something you may have wanted or needed yourself; Use charity money for military purposes if necessary.

This hadith is about a situation in which the Prophet Muhammad was commanding Abdullah ibn Amr ibn al-'As to equip an army, but there were not enough camels available. To solve this problem, he commanded him to keep back the young camels of sadaqah and replace them with two when more camels came. This hadith teaches us that it is permissible in Islam to use charity money for military purposes if necessary. It also teaches us that we should be wise and resourceful in times of need, as well as generous with our charity money even if it means sacrificing something we may have wanted or needed ourselves.
