Sahih al-Bukhari 2868
Narrated (`Abdullah) bin `Umar:
The Prophet (ﷺ) arranged for a horse race amongst the horses that had been made lean to take place 
between Al-Hafya'' and Thaniyat Al-Wada` (i.e. names of two places) and the horses which had not 
been mad.? lean from Ath-Thaniyat to the mosque of Bani Zuraiq. I was also amongst those who took 
part in that horse race. Sufyan, a sub-narrator, said, "The distance between Al-Hafya and Thaniya Al- 
Wada` is five or six miles; and between Thaniya and the mosque of Bani Zuraiq is one mile."
حَدَّثَنَا قَبِيصَةُ، حَدَّثَنَا سُفْيَانُ، عَنْ عُبَيْدِ اللَّهِ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ أَجْرَى النَّبِيُّ صلى الله عليه وسلم مَا ضُمِّرَ مِنَ الْخَيْلِ مِنَ الْحَفْيَاءِ إِلَى ثَنِيَّةِ الْوَدَاعِ، وَأَجْرَى مَا لَمْ يُضَمَّرْ مِنَ الثَّنِيَّةِ إِلَى مَسْجِدِ بَنِي زُرَيْقٍ‏.‏ قَالَ ابْنُ عُمَرَ وَكُنْتُ فِيمَنْ أَجْرَى‏.‏ قَالَ عَبْدُ اللَّهِ حَدَّثَنَا سُفْيَانُ قَالَ حَدَّثَنِي عُبَيْدُ اللَّهِ‏.‏ قَالَ سُفْيَانُ بَيْنَ الْحَفْيَاءِ إِلَى ثَنِيَّةِ الْوَدَاعِ خَمْسَةُ أَمْيَالٍ أَوْ سِتَّةٌ، وَبَيْنَ ثَنِيَّةِ إِلَى مَسْجِدِ بَنِي زُرَيْقٍ مِيلٌ‏.‏
