Musannaf Ibn Abi Shayba 27:43

Muhammad ibn Bishr narrated to us, Zakariya narrated to us, from Atiyyah, from Abu Sa’id, that the Prophet (peace and blessings of Allah be upon him) said: "Indeed, I have a basin whose length is between the Kaaba and Bayt al-Maqdis (Jerusalem). It is whiter than milk, and its vessels are like the number of the stars of the sky. And I will have the most followers among the prophets on the Day of Resurrection."
