Sahih Bukhari Volume 9, Book 96, Hadith 7338

حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا جُوَيْرِيَةُ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ، قَالَ سَابَقَ النَّبِيُّ صلى الله عليه وسلم بَيْنَ الْخَيْلِ، فَأُرْسِلَتِ الَّتِي ضُمِّرَتْ مِنْهَا وَأَمَدُهَا إِلَى الْحَفْيَاءِ إِلَى ثَنِيَّةِ الْوَدَاعِ، وَالَّتِي لَمْ تُضَمَّرْ أَمَدُهَا ثَنِيَّةُ الْوَدَاعِ إِلَى مَسْجِدِ بَنِي زُرَيْقٍ، وَأَنَّ عَبْدَ اللَّهِ كَانَ فِيمَنْ سَابَقَ‏.‏

Narrated By Nafi : 'Abdullah said, "The Prophet arranged for a horse race, and the prepared horses were given less food for a few days before the race to win the race, and were allowed to run from Al-Hafya to Thaniyat-al-Wada', and the unprepared horses were allowed to run between Thaniyat-al-Wada' and the mosque of Bani Zuraiq," 'Abdullah was one of those who participated in the race.
