وَحَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ - وَاللَّفْظُ لاِبْنِ الْمُثَنَّى - قَالاَ حَدَّثَنَا مُحَمَّدُ، بْنُ جَعْفَرٍ حَدَّثَنَا شُعْبَةُ، عَنْ أَبِي إِسْحَاقَ، قَالَ سَمِعْتُ الْبَرَاءَ، وَسَأَلَهُ، رَجُلٌ مِنْ قَيْسٍ أَفَرَرْتُمْ عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم يَوْمَ حُنَيْنٍ فَقَالَ الْبَرَاءُ وَلَكِنْ رَسُولُ اللَّهِ صلى الله عليه وسلم لَمْ يَفِرَّ وَكَانَتْ هَوَازِنُ يَوْمَئِذٍ رُمَاةً وَإِنَّا لَمَّا حَمَلْنَا عَلَيْهِمُ انْكَشَفُوا فَأَكْبَبْنَا عَلَى الْغَنَائِمِ فَاسْتَقْبَلُونَا بِالسِّهَامِ وَلَقَدْ رَأَيْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم عَلَى بَغْلَتِهِ الْبَيْضَاءِ وَإِنَّ أَبَا سُفْيَانَ بْنَ الْحَارِثِ آخِذٌ بِلِجَامِهَا وَهُوَ يَقُولُ " أَنَا النَّبِيُّ لاَ كَذِبْ أَنَا ابْنُ عَبْدِ الْمُطَّلِبْ " .
English Translation
It has been narrated through a still different chain of transmitters by the same narrator (i. e. Abu Ishaq) who said:I heard from Bara' who was asked by a man from the Qais tribe: Did you run away from the Messenger of Allah (ﷺ) on the Day of Hunain? Bara' said: But the Messenger of Allah (ﷺ) did not run away. On that day Banu Hawzzin took part in the battle as archers (on the side of the disbelievers). When we attacked them, they retreated and we fell upon the booty; (they rallied) and advanced towards us with arrows. (At that time) I saw the Messenger of Allah (ﷺ) riding on his white mule and Abu Sufyan b. al-Harith was holding its bridle. He (the Messenger of Allah was saying: I am the Prophet. This is no untruth. I am a descendant of 'Abd al-Muttalib)
