حَدَّثَنَا أَحْمَدُ بْنُ مُحَمَّدٍ، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا شُعْبَةُ، عَنْ قَتَادَةَ، سَمِعْتُ أَنَسَ بْنَ مَالِكٍ ـ رضى الله عنه ـ قَالَ كَانَ بِالْمَدِينَةِ فَزَعٌ، فَاسْتَعَارَ النَّبِيُّ صلى الله عليه وسلم فَرَسًا لأَبِي طَلْحَةَ، يُقَالُ لَهُ مَنْدُوبٌ فَرَكِبَهُ، وَقَالَ " مَا رَأَيْنَا مِنْ فَزَعٍ، وَإِنْ وَجَدْنَاهُ لَبَحْرًا ".
There was a feeling of fright in Medina, so the Prophet (ﷺ) borrowed a horse called Mandub belonging 'to Abu Talha and mounted it. (On his return), he said, "I did not see anything of fright and I found this horse very fast."
