حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، حَدَّثَنَا اللَّيْثُ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ ـ رضى الله عنه أَنَّ النَّبِيَّ صلى الله عليه وسلم سَابَقَ بَيْنَ الْخَيْلِ الَّتِي لَمْ تُضَمَّرْ، وَكَانَ أَمَدُهَا مِنَ الثَّنِيَّةِ إِلَى مَسْجِدِ بَنِي زُرَيْقٍ. وَأَنَّ عَبْدَ اللَّهِ بْنَ عُمَرَ كَانَ سَابَقَ بِهَا. قَالَ أَبُو عَبْد اللَّهِ أَمَدًا غَايَةً فَطَالَ عَلَيْهِمْ الْأَمَدُ
