Sahih Muslim Hadith 4612

I was in the company of the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌) on the Day of Hunain. I and Abu Sufyan bin Harith bin 'Abdul-Muttalib رضی اللہ عنہ stuck to the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌) 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 bin Nufitha al-Judhami. When the Muslims had an encounter with the disbelievers, the Muslims fled, falling back, but the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌) began to spur his mule towards the disbelievers. I was holding the bridle of the mule of the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) checking it from going very fast, and Abu Sufyan رضی اللہ عنہ was holding the stirrup of the (mule of the) Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌), who said: Abbas رضی اللہ عنہ , call out to the people of al-Samura. Abbas رضی اللہ عنہ (who was a man with a loud voice) called out at the top of the voice: Where are the people of Samura? (Abbas رضی اللہ عنہ 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 رضی اللہ عنہ 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 bin al-Khazraj! O Banu Harith bin al-Khazraj! And the Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) 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 ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) 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 رضی اللہ عنہ 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.
