سنن النسائي

It was narrated from Ibn Abbas that Usmah bin Zaid said: "The Messneger of Allah departed from Arafat and I was riding behind him. He started trying to rein in his camel until its ears nearly touched the front of the saddle, and he was saying: 'O people, you must be tranquil and dignified, for righteousness does not come by making camels hurry.'"
