Sahih Muslim , Book 19, Hadith 4385 (USC-MSA) ⓘ

It has been narrated on the authority of 'Abbas who said: I was in the company of the Messenger of Allah on the Day of Hunain. I and Abd Sufyan b. Harith b. 'Abd al-Muttalib stuck to the Messenaer of Allah and we did not separate from him. And the Messenger of Allah (may place be upon him) was riding on his white mule which had been presented to him by Farwa b. Nufitha al-Judhami. When the Muslims had an encounter with the disbelievers, the Muslims fled, falling back, but the Messenger of Allah began to spur his mule towards the disbelievers. I was holding the bridle of the mule of the Messenger of Allah checking it from going very fast, and Abu Sufyan was holding the stirrup of the (mule of the) Messenger of Allah, who said: Abbas, call out to the people of al-Samura. Abbas (who was a man with a loud voice) called out at the top of the voice: Where are the people of Samura? (Abbas said: ) And by God, when they heard my voice, they came back (to us) as cows come back to their calves, and said: We are present, we are present! 'Abbas said: They began to fight the infidels. Then there was a call to The Ansar. Those (who called out to them) shouted: O ye party of the Ansar! O party of the Ansar! Banu al-Harith b. al-Khazraj were the last to be called. Those (who called out to them) shouted: O Banu Al-Harith b. al-Khazraj! O BanU Harith b. al-Khazraj! And the Messenger of Allah who was riding on his mule looked at their fight with his neck stretched forward and he said: This is the time when the fight is raging hot. Then the Messenger of Allah took (some) pebbles and threw them in the face of the infidels. Then he said: By the Lord of Muhammad, the infidels are defeated. 'Abbas said: I went round and saw that the battle was in the same condition in which I had seen it. By Allah, it remained in the same condition until he threw the pebbles. I continued to watch until I found that their force had been spent out and they began to retreat.
