Nafi' bin Jubayr (may Allah have mercy on him) narrates from his father, Sayyiduna Jubayr bin Mut'im (may Allah be pleased with him), that the Prophet (peace and blessings be upon him) said: "All of Arafah is a place of standing, but keep away from (the valley of) Uranah; all of Muzdalifah is a place of standing, but keep away from Batn Muhassir; all the days of Tashriq are days of sacrifice; and all the paths of Makkah are a place of slaughter."
