Sahih Ibn Khuzaymah

Sayyiduna Jubair bin Mut’im (may Allah be pleased with him) narrates that the people of Quraysh used to return from Muzdalifah and would say, “We are Hums (firm and better people in religion), so we will not go outside the boundaries of the Haram.” These people had abandoned the standing at Arafat. He says, “I saw the Messenger of Allah (peace and blessings be upon him) with the people in the plain of Arafat, mounted on his camel. Then in the morning, he would join his people at Muzdalifah, and he would stay with them until when they returned towards Mina, he would set out with them.”
