Yusuf bin Hmad يوسف بن حماد · The Book on Jihad

"Indeed we saw the day of Hunain, and indeed the two armies fled from the Messenger of Allah (ﷺ), and there did not remain one hundred men with the Messenger of Allah (ﷺ)." This Hadith is Hasan Gharib as a narration of 'Ubaidullah. We do not know of it except from this route.
