We have found no reason for consternation, and we have found it to be (as quick as a torrent) of water. (Using translation from Muslim 2307b)
كَانَ بِالْمَدِينَةِ فَزَعٌ فَاسْتَعَارَ النَّبِيُّ ﷺ فَرَسًا لِأَبِي طَلْحَةَ يُقَالُ لَهُ مَنْدُوبٌ فَرَكِبَهُ ثُمَّ جَاءَ فَقَالَ مَا رَأَيْنَا مِنْ فَزَعٍ وَإِنْ وَجَدْنَاهُ لَبَحْرًا
