Al-Qasim bin Abdur-Rahman narrated that his father said: ’Abdullah bin Mas'ood said:

I was with the Messenger of Allah (ﷺ) at Hunain. The people fled and left him, but eighty men of the Muhajireen and Ansar stood fast with him. We fell back about eighty steps but we did not turn our backs, and they are the ones upon whom Allah sent down tranquillity (as-sakeenah). The Messenger of Allah (ﷺ) was on his mule going forward, but the mule veered and he tilted and was about to fall. I said to him. Rise up, may Allah lift you high. And he said: "Give me a handful of dust,” and threw it at their faces, and their eyes were filled with dust. Then he said: Where are the Muhajireen and Ansar? I said: Here they are. He said: Call them. So I called them and they came (swiftly) like meteors, with their swords in their right hands, and the mushrikeen turned and fled.
