Nafi' bin Jubayr bin Mut'im (may Allah have mercy on him) narrates from his father, Sayyiduna Jubayr bin Mut'im (may Allah be pleased with him), who said: Quraysh used to depart only from Muzdalifah. They would say: We are the Hums, we do not go out of the Haram. And they had abandoned the standing at Arafah. Then I saw the Messenger of Allah (peace and blessings be upon him) standing with the people at Arafah on one of his camels, and he would depart with them, until he would spend the morning with his people at Muzdalifah, stay there with them, and then when they departed, he (peace and blessings be upon him) would depart as well.
