Musnad Ahmad 789:44

'Abd al-Samad narrated to us, 'Abd al-Salam Abu Talut narrated to us, al-'Abbas al-Jurayri narrated to us, that 'Ubayd Allah ibn Ziyad said to Abu Barzah: "Did you ever hear the Prophet, may Allah bless him and grant him peace, mention it?"—meaning the Basin (al-Hawd). He said: "Yes, not once, nor twice. So whoever denies it, may Allah not let him drink from it."
