Narrated Abu 'Is-haq from Musa bin `Uqba from Mafia from Ibn `Umar who said:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ ، حَدَّثَنَا مُعَاوِيَةُ ، حَدَّثَنَا أَبُو إِسْحَاقَ ، عَنْ مُوسَى بْنِ عُقْبَةَ ، عَنْ نَافِعٍ ، عَنِ ابْنِ عُمَرَ ـ رضى الله عنهما ـ قَالَ سَابَقَ رَسُولُ اللَّهِ صلى الله عليه وسلم بَيْنَ الْخَيْلِ الَّتِي قَدْ أُضْمِرَتْ فَأَرْسَلَهَا مِنَ الْحَفْيَاءِ، وَكَانَ أَمَدُهَا ثَنِيَّةَ الْوَدَاعِ. فَقُلْتُ لِمُوسَى فَكَمْ كَانَ بَيْنَ ذَلِكَ قَالَ سِتَّةُ أَمْيَالٍ أَوْ سَبْعَةٌ. وَسَابَقَ بَيْنَ الْخَيْلِ الَّتِي لَمْ تُضَمَّرْ، فَأَرْسَلَهَا مِنْ ثَنِيَّةِ الْوَدَاعِ، وَكَانَ أَمَدُهَا مَسْجِدَ بَنِي زُرَيْقٍ، قُلْتُ فَكَمْ بَيْنَ ذَلِكَ قَالَ مِيلٌ أَوْ نَحْوُهُ. وَكَانَ ابْنُ عُمَرَ مِمَّنْ سَابَقَ فِيهَا.
"Allah's Messenger (ﷺ) arranged a horse race amongst the horses that had been made lean, letting them start from Al-Hafya' and their limit (distance of running) was up to Thaniyat-al-Wada`. I asked Musa, 'What was the distance between the two places?' Musa replied, 'Six or seven miles. He arranged a race of the horses which had not been made lean sending them from Thaniyat-al-Wada`, and their limit was up to the mosque of Bani Zuraiq.' I asked, 'What was the distance between those two places?' He replied 'One mile or so.' Ibn `Umar was amongst those who participated in that horse race."
