"...the Messenger of Allah (may Allah bless him and grant him peace) used to go out on military expeditions or send out an army at least every two months. The virtuous Companions continued upon the path of the Noble Prophet (may Allah bless him and grant him peace), for the Glorious Qur'an had brought up this generation with an education of Jihad. They had been bathed in Jihad and cleansed of engrossment in worldly matters, just as a wound is bathed in water." - Imam Abdullah Azzam
