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.
