Sayyiduna al-Bara' bin Azib (may Allah be pleased with him) said that a man said: O Abu Umarah! Did you flee on the Day of Hunayn? He said: I bear witness that the Prophet (peace and blessings be upon him) did not flee; but when Hawazin showered arrows upon the hasty ones among the people, and Sayyiduna Abu Sufyan (may Allah be pleased with him) was holding the reins of his (peace and blessings be upon him) white mule, he (peace and blessings be upon him) was saying: "I am the Prophet, it is no lie; I am the son of Abd al-Muttalib."
