It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that he said: I was with the Messenger of Allah (peace and blessings be upon him) on the day of Hunayn. The people fell back from him, but I remained firm with him along with eighty (80) men of the Muhajirun and Ansar. We stood firm on our feet at a distance of about eighty (80) paces and did not turn our backs; these were the ones upon whom Allah sent down tranquillity (sakinah). The narrator says: the Messenger of Allah (peace and blessings be upon him) was riding his mule, advancing forward. His mule shied, and he (peace and blessings be upon him) leaned to one side of the saddle. Then he (peace and blessings be upon him) steadied himself, and I said: "O Messenger of Allah, may Allah keep your rank high." He (peace and blessings be upon him) said: "Hand me a handful of dust." I handed him the dust, and he (peace and blessings be upon him) threw it at their (the polytheists') faces, and their eyes were filled with dust. Then he (peace and blessings be upon him) said: "Where are the Muhajirun and the Ansar?" I said: "They are right here." He (peace and blessings be upon him) said: "Call out to them." I called out to them, and they rushed forward with their swords in their right hands as though they were shooting stars (meteors), and the polytheists turned their backs and fled. This hadith has a sahih (authentic) chain of narration, but the two Shaykhs (Bukhari and Muslim) did not record it.
