(15) باب مَا جَاءَ فِي الثَّبَاتِ عِنْدَ الْقِتَالِ
Narrated Abu Ishaq:
From Al-Bara' bin 'Azib who said: "A man said to us: 'Did you flee from the Messenger of Allah (ﷺ) O Abu 'Umarah ?'" He said: "No, By Allah! I did not flee from the Messenger of Allah (ﷺ), but som hasty people fled and (the tribe of) Hawazin assaulted them with arrows. The Messenger of Allah (Saws) was on his white muls, and Abu Sufyan bin Al-Harith bin 'Abdul Muttalib was holding its reigns. The Messenger of Allah (ﷺ) was saying: 'I am the Prophet without lie, I am the son of 'Abdul-Muttalib.'"[Abu 'Eisa said:] There are narrations on this topic from 'Ali, and Ibn 'Umar.
