What is the battle in which Uqbah was victorious over the Byzantines in Barqa?

No name was mentioned for the Battle of Barqa. Rather, it was opened peacefully by 'Amr ibn al-'As in 22 AH, after his conquest of Egypt, with the aim of securing his conquests from the west due to the presence of Roman forces there. Its people made peace with him on the condition of paying jizya, which they would send to the governor of Egypt without a tax collector. 'Amr then directed 'Uqbah ibn Nafi' to conquer Zawila, thus making the area between Barqa and Zawila Muslim territory.
