Musannaf Ibn Abi Shayba 27:49

Abu Mu'awiyah narrated to us, from al-A'mash, from 'Amr ibn Murrah, from Talhah, the freed slave of Qurzah, from Zayd ibn Arqam, who said: The Messenger of Allah (peace be upon him) said: "You are not one part out of one hundred thousand parts of those who will come to the Basin (al-Hawd)." We said to Zayd: "How many were you on that day?" He said: "Between six hundred and seven hundred."
