Musannaf Ibn Abi Shayba 27:30

Hashim ibn al-Qasim narrated to us, [saying] Abd al-Rahman ibn Abd Allah ibn Dinar narrated to us, from Abu Hazim, from Sahl ibn Sa’d, who said: The Messenger of Allah (may Allah bless him and grant him peace) said: "I am your forerunner at the Basin (al-Hawd). Whoever comes to me shall drink from it, and whoever drinks from it shall never thirst again."
