Musnad Abu Ya'la al-Mawsili 118:52

Muhammad ibn 'Abbad narrated to us, Abu Damrah narrated to us, from Yunus, from al-Zuhri, from Anas, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "Indeed, my Basin is [the distance] between Ayla and San'a of Yemen. And indeed, there are in it [vessels] like the number of the stars of the sky."
