It is narrated from Sayyiduna Usama bin Zaid (may Allah be pleased with him), who was riding with the Messenger of Allah (peace and blessings be upon him) when he set out from Arafat towards Muzdalifah: and the Messenger of Allah (peace and blessings be upon him) would make the camel go a little faster, and when he found an open space, he would make it go even faster.
