It is narrated from Sayyiduna Zayd bin Arqam (may Allah be pleased with him); he said: The Messenger of Allah (peace and blessings be upon him) said to us: "You are not even one part out of a hundred thousand parts of those who will come to me at the Pond (al-Hawd)." We asked Zayd: "How many were you that day?" He said: "Between six hundred and seven hundred."
