Musannaf Ibn Abi Shayba 27:50

Husayn ibn Ali narrated to us, from Za'idah, from 'Asim, from Zirr, from Hudhayfah, who said: The Basin (al-Hawd) is whiter than milk, sweeter than honey, colder than snow, and more pleasant in scent than musk. Its vessels are the number of the stars of the sky. Its distance is between Ayla and San'a. Whoever drinks from it will never thirst after that, ever.
