Muwatta Imam Malik (Riwayat Ibn al-Qasim)

It is narrated from Urwah bin Zubair (may Allah have mercy on him) that I was sitting (there) when Sayyiduna Usama bin Zaid (may Allah be pleased with him) was asked how the Messenger of Allah (peace and blessings be upon him) used to walk during the return from Arafat in the Farewell Pilgrimage. He replied: The Messenger of Allah (peace and blessings be upon him) would walk briskly and with wide steps, and when he found an open space, he would walk even faster. Hisham (bin Urwah, the narrator of the hadith) said: "Anaq" is less than "nas" (in speed; "nas" means walking even faster).
