It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) held a horse race: he sent them off from al-Hayfa', and their finishing point was Thaniyyat al-Wada'. He also held a race for the horses that had not been conditioned, and their course was from the Thaniyyah to the Mosque of Banu Zurayq.
