Musnad Ahmad 937:39

'Abd al-'Aziz ibn 'Abd al-Samad narrated to us, Abu 'Imran al-Jawni narrated to us, from 'Abd Allah ibn al-Samit, from Abu Dharr, who said: I said: "O Messenger of Allah, what are the vessels of the Basin (al-Hawd)?" He said: "By Him in Whose hand is my soul, its vessels are more numerous than the number of the stars of the sky and its planets on a dark, clear night. They are the vessels of Paradise; whoever drinks from them will never thirst after that. Two spouts flow into it from Paradise; whoever drinks from it will never thirst. Its width is equal to its length, from 'Amman to Ayla. Its water is whiter than milk and sweeter than honey."
