Once the people got frightened, so Messenger of Allah ﷺ rode a slow horse belonging to Abu Talha, and he set out all alone, making the horse gallop. Then the people rode, making their horses gallop after him. On his return he said, "Don't be afraid (there is nothing to be afraid of) (and I have found) this horse a very fast one." That horse was never excelled in running hence forward. (Qastalani Vol. 5) (Using translation from Bukhārī 2969)   

البيهقي:٢٠٨٤٩ – أَخْبَرَنَا أَبُو عَبْدِ اللهِ الْحَافِظُ ثنا أَبُو الْعَبَّاسِ مُحَمَّدُ بْنُ يَعْقُوبَ ثنا جَعْفَرُ بْنُ مُحَمَّدِ بْنِ شَاكِرٍ ثنا حُسَيْنُ بْنُ مُحَمَّدٍ الْمَرْوَرُّوذِيُّ ثنا جَرِيرٌ عَنْ مُحَمَّدٍ عَنْ أَنَسٍ قَالَ

فَزِعَ النَّاسُ فَرَكِبَ النَّبِيُّ ﷺ فَرَسًا لِأَبِي طَلْحَةَ بَطِيئًا ثُمَّ خَرَجَ يَرْكُضُ وَحْدَهُ فَرَكِبَ النَّاسُ يَرْكُضُونَ خَلْفَهُ فَقَالَ لَنْ تُرَاعُوا إِنَّهُ لَبَحْرٌ  

رَوَاهُ الْبُخَارِيُّ فِي الصَّحِيحِ عَنِ الْفَضْلِ بْنِ سَهْلٍ عَنْ حُسَيْنِ بْنِ مُحَمَّدٍ
