Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)
Bukhari :: Book 5 :: Volume 59 :: Hadith 605
Narrated Abu Ishaq:
I heard Al-Bara' narrating when a man came and said to him, "O Abu 'Umara! Did you flee on the day (of the battle) of Hunain?" Al-Bara' replied, "I testify that the Prophet did not flee, but the hasty people hurried away and the people of Hawazin threw arrows at them. At that time, Abu Sufyan bin Al-Harith was holding the white mule of the Prophet by the head, and the Prophet was saying, "I am the Prophet undoubtedly: I am the son of 'Abdul-Muttalib."
