Narrated Al-Bara' bin 'Azib:
On the day of Uhud the Prophet appointed 'Abdullah bin Jubair as chief of the archers, and seventy among us were injured and martyred. On the day (of the battle) of Badr, the Prophet and his companions had inflicted 140 casualties on the pagans, 70 were taken prisoners, and 70 were killed. Abu Sufyan said, "This is a day of (revenge) for the day of Badr and the issue of war is undecided ."
