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.
