عَنْ أَنَسِ بْنِ مَالِكٍ رَضِيَ اللَّهُ عَنْهُ قَالَ كَانَ فَزَعٌ بِالْمَدِينَةِ فَاسْتَعَارَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَرَسًا لَنَا يُقَالُ لَهُ مَنْدُوبٌ قَالَ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ مَا وَجَدْنَا مِنْ فَزَعٍ وَإِنْ وَجَدْنَاهُ لَبَحْرًا قَالَ حَجَّاجٌ يَعْنِي الْفَرَسَ
It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that once a sense of fear arose in Madinah Munawwarah. The Messenger of Allah, peace and blessings be upon him, borrowed a horse from us, which was called Mandub. Upon returning, he, peace and blessings be upon him, said: "There is nothing to fear." We found this horse (in speed) like the sea.
