Ibn Kathir writes that according to Ibn Ishaq, Jabir ibn Abd Allah, who witnessed the battle, reported that the Muslim army were panicked by a surprise attack from the enemy and many men fled the battlefield. However, a group of Muhajirun stood firmly and defended Muhammad on the battlefield. These men were Abu Bakr, Umar, Ali, Abbas ibn Abd al-Muttalib, Abu Sufyan ibn al-Harith, Fadl ibn Abbas, Rabi'ah ibn al-Harith, Usama ibn Zayd and Ayman ibn Ubayd.
