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."

حَدَّثَنَا مُحَمَّدُ بْنُ كَثِيرٍ، حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي إِسْحَاقَ، قَالَ سَمِعْتُ الْبَرَاءَ، رضى الله عنه وَجَاءَهُ رَجُلٌ فَقَالَ يَا أَبَا عُمَارَةَ أَتَوَلَّيْتَ يَوْمَ حُنَيْنٍ فَقَالَ أَمَّا أَنَا فَأَشْهَدُ عَلَى النَّبِيِّ ﷺ أَنَّهُ لَمْ يُوَلِّ، وَلَكِنْ عَجِلَ سَرَعَانُ الْقَوْمِ، فَرَشَقَتْهُمْ هَوَازِنُ، وَأَبُو سُفْيَانَ بْنُ الْحَارِثِ آخِذٌ بِرَأْسِ بَغْلَتِهِ الْبَيْضَاءِ يَقُولُ {أَنَا النَّبِيُّ لاَ كَذِبْ، أَنَا ابْنُ عَبْدِ الْمُطَّلِبْ}.
