Once there was a feeling of fright at Medina, so Messenger of Allah ﷺ rode a horse belonging to Abu Talha and (on his return) he said, "We have not seen anything (fearful), but we found this horse very fast."  

كَانَ بِالْمَدِينَةِ فَزَعٌ فَرَكِبَ رَسُولُ اللَّهِ ﷺ فَرَسًا لأَبِي طَلْحَةَ فَقَالَ مَا رَأَيْنَا مِنْ شَىْءٍ وَإِنْ وَجَدْنَاهُ لَبَحْرًا
