In 625 A.D. (3 H.), the Muslims of Madinah
learned a difficult lesson during the Battle of Uhud. When attacked by an invading army from Makkah, it initially looked like the small group of defenders would win the battle. But at a key moment, some fighters disobeyed orders and left their posts out of greed and pride, ultimately causing the Muslim army a crushing defeat. It was a trying time in the history of Islam.
