"There was a cause of fright in Al-Madinah. So the Messenger of Allah ﷺ borrowed a horse of ours called Mandub. He said: 'I have not seen anything to be frightened of, and we found him to be (quick) like the sea.'" (Using translation from Tirmidhī 1686)
كَانَ فَزَعٌ بِالْمَدِينَةِ فَاسْتَعَارَ رَسُولُ اللهِ ﷺ فَرَسًا لَنَا يُقَالُ لَهُ مَنْدُوبٌ فَقَالَ رَسُولُ اللهِ ﷺ مَا رَأَيْنَا مِنْ فَزَعٍ وَإِنْ وَجَدْنَاهُ لَبَحْرًا
