Narrated Anas bin Malik:
حَدَّثَنَا عَبْدُ الأَعْلَى بْنُ حَمَّادٍ ، حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ ، حَدَّثَنَا سَعِيدٌ ، عَنْ قَتَادَةَ ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه أَنَّ أَهْلَ، الْمَدِينَةِ فَزِعُوا مَرَّةً، فَرَكِبَ النَّبِيُّ صلى الله عليه وسلم فَرَسًا لأَبِي طَلْحَةَ كَانَ يَقْطِفُ ـ أَوْ كَانَ فِيهِ قِطَافٌ ـ فَلَمَّا رَجَعَ قَالَ " وَجَدْنَا فَرَسَكُمْ هَذَا بَحْرًا ". فَكَانَ بَعْدَ ذَلِكَ لاَ يُجَارَى.
Once the people of Medina were frightened, so the Prophet (ﷺ) rode a horse belonging to Abu Talha and it ran slowly, or was of narrow paces. When he returned, he said, "I found your (i.e. Abu Talha's) horse very fast. After that the horse could not be surpassed in running..'
