Battle of Uhud

"A devout Muslim Uwayah Qami lived in the valley of Urfa. He told Umar... that “when I learnt that a tooth of the Prophet had been martyred (in the Battle of Uhud) I broke one of mine. Then I thought that perhaps some other tooth of his had been martyred. So, I broke all my teeth… It is only after that that I felt at peace”."

"After Uhud came revelations to explain the setback. While Badr was Allah’s victory, Uhud was not Allah’s defeat but the result of the Muslims’ failure of courage and lust for the things of this world, specifically in this case the spoils of war, the goods and women they hoped to win from the Quraysh."
