Musnad Ahmad 25:261

Waki’ narrated to us, from al-Mas’udi, from al-Hakam, from Miqsam, from Ibn Abbas: That the Prophet, peace and blessings of Allah be upon him, when he departed from Arafat, some people hastened. He said: Or it was called out: "Righteousness is not in the hastening of horses, nor of camels." He said: "So I did not see any [animal] raising its forelegs and running until we reached Jam’."
