عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ رَضِيَ اللَّهُ عَنْهُمَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ سَبَّقَ بَيْنَ الْخَيْلِ وَفَضَّلَ الْقُرَّحَ فِي الْغَايَةِ
It is narrated from Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) held races between horses and declared those horses superior which had entered their fifth year of age.
