Sahih al-Bukhari 4317
Narrated Abu 'Is-haq:
That he heard Al-Bara narrating when a man from Qais (tribe) asked him "Did you flee leaving 
Allah's Messenger (ﷺ) on the day (of the battle) of Hunain?" Al-Bara' replied, "But Allah's Messenger (ﷺ) did not 
flee. The people of Hawazin were good archers, and when we attacked them, they fled. But rushing 
towards the booty, we were confronted by the arrows (of the enemy). I saw the Prophet (ﷺ) riding his 
white mule while Abu Sufyan was holding its reins, and the Prophet (ﷺ) was saying "I am the Prophet (ﷺ) 
undoubtedly." (Israil and Zuhair said, "The Prophet (ﷺ) dismounted from his Mule.")
حَدَّثَنِي مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا غُنْدَرٌ، حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، سَمِعَ الْبَرَاءَ ـ وَسَأَلَهُ رَجُلٌ مِنْ قَيْسٍ ـ أَفَرَرْتُمْ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم يَوْمَ حُنَيْنٍ فَقَالَ لَكِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم لَمْ يَفِرَّ، كَانَتْ هَوَازِنُ رُمَاةً، وَإِنَّا لَمَّا حَمَلْنَا عَلَيْهِمِ انْكَشَفُوا، فَأَكْبَبْنَا عَلَى الْغَنَائِمِ، فَاسْتُقْبِلْنَا بِالسِّهَامِ، وَلَقَدْ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَلَى بَغْلَتِهِ الْبَيْضَاءِ، وَإِنَّ أَبَا سُفْيَانَ آخِذٌ بِزِمَامِهَا وَهْوَ يَقُولُ ‏{‏أَنَا النَّبِيُّ لاَ كَذِبْ‏}‏‏.‏ قَالَ إِسْرَائِيلُ وَزُهَيْرٌ نَزَلَ النَّبِيُّ صلى الله عليه وسلم عَنْ بَغْلَتِهِ‏.‏
