Once the people of Medina were frightened, so the Prophet ﷺ borrowed a horse from Abu Talha called Al-Mandub, and rode it. When he came back he said, "We have not seen anything (to be afraid of), but the horse was very fast (having an energy as inexhaustible as the water of the sea). (Using translation from Bukhārī 2627)
سَمِعْتُ أَنَسَ بْنَ مَالِكٍ يَقُولُ كَانَ فَزَعٌ بِالْمَدِينَةِ فَاسْتَعَارَ رَسُولُ اللهِ ﷺ فَرَسًا مِنْ أَبِي طَلْحَةَ يُقَالُ لَهُ الْمَنْدُوبُ فَرَكِبَهُ فَلَمَّا رَجَعَ قَالَ مَا رَأَيْنَا مِنْ شَيْءٍ وَإِنْ وَجَدْنَاهُ لَبَحْرًا
