Sahih Muslim 1776 a
It has been narratedon the authority of Abu Ishaq who said:
A man asked Bara' (b. 'Azib): Did you run away on the Day of Hunain. O, Abu Umira? He said: No, by Allah, The Messenger of Allah (ﷺ) did not turn his back; (what actually happened was that) some young men from among his companions, who were hasty and who were either without any arms or did not have abundant arms, advanced and met a party of archers (who were so good shots) that their arrows never missed the mark. This party (of archers) belonged to Banu Hawazin and Banu Nadir. They shot at the advancing young men and their arrows were not likely to miss their targets. So these young men turned to the Messenger of Allah (ﷺ) while he was riding on his white mule and Abu Sufyan b. al-Harith b. 'Abd al-Muttalib was leading him. (At this) he got down from his mule, invoked God's help, and called out: I am the Prophet. This is no untruth. I am the son of 'Abd al-Muttalib. Then he deployed his men into battle array.
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، أَخْبَرَنَا أَبُو خَيْثَمَةَ، عَنْ أَبِي إِسْحَاقَ، قَالَ قَالَ رَجُلٌ لِلْبَرَاءِ يَا أَبَا عُمَارَةَ أَفَرَرْتُمْ يَوْمَ حُنَيْنٍ قَالَ لاَ وَاللَّهِ مَا وَلَّى رَسُولُ اللَّهِ صلى الله عليه وسلم وَلَكِنَّهُ خَرَجَ شُبَّانُ أَصْحَابِهِ وَأَخِفَّاؤُهُمْ حُسَّرًا لَيْسَ عَلَيْهِمْ سِلاَحٌ أَوْ كَثِيرُ سِلاَحٍ فَلَقُوا قَوْمًا رُمَاةً لاَ يَكَادُ يَسْقُطُ لَهُمْ سَهْمٌ جَمْعَ هَوَازِنَ وَبَنِي نَصْرٍ فَرَشَقُوهُمْ رَشْقًا مَا يَكَادُونَ يُخْطِئُونَ فَأَقْبَلُوا هُنَاكَ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم وَرَسُولُ اللَّهِ صلى الله عليه وسلم عَلَى بَغْلَتِهِ الْبَيْضَاءِ وَأَبُو سُفْيَانَ بْنُ الْحَارِثِ بْنِ عَبْدِ الْمُطَّلِبِ يَقُودُ بِهِ فَنَزَلَ فَاسْتَنْصَرَ وَقَالَ ‏
"‏ أَنَا النَّبِيُّ لاَ كَذِبْ أَنَا ابْنُ عَبْدِ الْمُطَّلِبْ ‏"‏ ‏.‏ ثُمَّ صَفَّهُمْ ‏.‏
