Jubair bin Mut’im (may Allah be pleased with him) says that (before accepting Islam) on the day of Arafah, one of my camels was lost. I went out to search for it, and I saw the Prophet Muhammad (peace and blessings of Allah be upon him) standing at Arafat. So I said to myself,“By Allah, he is from the people of Hums (the strict people, i.e., the Quraysh), so what is he doing here?”
