Urwah (may Allah have mercy on him) said: Sayyiduna Usamah bin Zayd (may Allah be pleased with them both) was asked, while I was sitting there, how the Prophet (peace and blessings be upon him) travelled on the occasion of the Farewell Hajj when returning. He said: "He would travel at a moderate pace, and when he found an open space he would make his mount go fast."
Hisham said: al-nass (going fast) is faster than al-'anaq (a moderate pace).
