The people of Madina were started. The Messenger of Allah ﷺ rode on the horse belonging to Abu Talhah. He said: We did not see anything, or he said: we did not see (find) any fear. I found it (could run) like a river.

حَدَّثَنَا عَمْرُو بْنُ مَرْزُوقٍ، أَخْبَرَنَا شُعْبَةُ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، قَالَ كَانَ فَزَعٌ بِالْمَدِينَةِ فَرَكِبَ رَسُولُ اللَّهِ ﷺ فَرَسًا لأَبِي طَلْحَةَ فَقَالَ " مَا رَأَيْنَا شَيْئًا " . أَوْ " مَا رَأَيْنَا مِنْ فَزَعٍ وَإِنْ وَجَدْنَاهُ لَبَحْرًا " .
