Musannaf Ibn Abi Shayba 30:149

"Abd al-Aziz ibn Abd al-Samad narrated to us, from Abu Imran al-Jawni, from Abdullah ibn al-Samit, from Abu Dharr, who said: I said, 'O Messenger of Allah, what are the vessels of the Basin?' He said, 'By the One in Whose hand is my soul, its vessels are more numerous than the number of the stars and planets of the sky on a dark, clear night. Whoever drinks from it will never thirst. Its width is equal to its length, between Amman and Ayla. Its water is whiter than milk and sweeter than honey.'"
