حَدَّثَنَا عَبْدُ اللَّهِ بْنُ يُوسُفَ، قَالَ أَخْبَرَنَا مَالِكٌ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم سَابَقَ بَيْنَ الْخَيْلِ الَّتِي أُضْمِرَتْ مِنَ الْحَفْيَاءِ، وَأَمَدُهَا ثَنِيَّةُ الْوَدَاعِ، وَسَابَقَ بَيْنَ الْخَيْلِ الَّتِي لَمْ تُضْمَرْ مِنَ الثَّنِيَّةِ إِلَى مَسْجِدِ بَنِي زُرَيْقٍ، وَأَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ كَانَ فِيمَنْ سَابَقَ بِهَا.
