Ash-Shama'il Al-Muhammadiyah, Book 36, Hadith 234 (English) ⓘ

Baraa ibn Aazib radiyallahu anhu was once asked, You all deserted Rasoolullah sallallahu alaihe wasallam and ran away in the Battle of Hunayn? He replied, No, Rasoolullah sallallahu alaihe wasallam did not turn away, except a few people in the army who were in a hurry (many of whom were from the tribe of Sulaym and a few newly converted youth of Makkah) turned away when the people of the tribe of Hawaazin began to shower arrows. Rasoolullah sallallahu alaihe wasallam (with whom there naturally were the great Sahaabah radiyallahu anhum) was riding a mule Abu Sufyan ibn Al-Haarith ibn Abdul Muttalib radiyallahu anhu was leading it by its reins. Sayyidina Rasoolullah sallallahu alaihe wasallam was reciting the following couplet: Verily, without doubt I am a Prophet. I am from the children (grandsons) of Abdul Muttalib

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، قَالَ‏:‏ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، قَالَ‏:‏ حَدَّثَنَا سُفْيَانُ الثَّوْرِيُّ، قَالَ‏:‏ أَنْبَأَنَا أَبُو إِسْحَاقَ، عَنِ الْبَرَاءِ بْنِ عَازِبٍ، قَالَ‏:‏ قَالَ لَهُ رَجُلٌ‏:‏ أَفَرَرْتُمْ عَنْ رَسُولِ اللهِ صلى الله عليه وسلم يَا أَبَا عُمَارَةَ‏؟‏ فَقَالَ‏:‏ لا وَاللَّهِ مَا وَلَّى رَسُولُ اللهِ صلى الله عليه وسلم، وَلَكِنْ وَلَّى سَرَعَانُ النَّاسِ، تَلَقَّتْهُمْ هَوَازِنُ بِالنَّبْلِ، وَرَسُولُ اللهِ صلى الله عليه وسلم، عَلَى بَغْلَتِهِ، وَأَبُو سُفْيَانَ بْنُ الْحَارِثِ بْنِ عَبْدِ الْمُطَّلِبِ آخِذٌ بِلِجَامِهَا، وَرَسُولُ اللهِ يَقُولُ‏:‏ أَنَا النَّبِيُّ لا كَذِبْ أَنَا ابْنُ عَبْدِ الْمُطَّلِبْ‏.‏
