Hadith 8:1333
Abu Bakr narrated to us, he said: Hatim ibn Isma'il narrated to us, from Ja'far, from his father, from Jabir: That the Prophet, peace and blessings of Allah be upon him, came to Arafat. When the sun had declined, he ordered the Qaswa (his she-camel), and it was saddled for him. He then came to the bottom of the valley and addressed the people.
