Narrated Anas bin Malik:

Once there was a feeling of fright at Medina, so Allah's Apostle rode a horse belonging to Abu Talha and (on his return) he said, "We have not seen anything (fearful), but we found this horse very fast."

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنْ شُعْبَةَ، حَدَّثَنِي قَتَادَةُ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ كَانَ بِالْمَدِينَةِ فَزَعٌ، فَرَكِبَ رَسُولُ اللَّهِ ﷺ فَرَسًا لأَبِي طَلْحَةَ، فَقَالَ " مَا رَأَيْنَا مِنْ شَىْءٍ، وَإِنْ وَجَدْنَاهُ لَبَحْرًا ".
