Musannaf Ibn Abi Shayba 27:42

Ya'la ibn 'Ubayd narrated to us, from Abu Hayyan, from Yazid ibn Hayyan, from Zayd ibn Arqam: He said: 'Ubayd Allah ibn Ziyad sent for me, so I came to him. He said: "What are these hadiths you narrate, which have reached us, and you report them from the Messenger of Allah (may Allah bless him and grant him peace), which we do not hear in any book of his? And you narrate that he has a Hawd (Cistern)." He (Zayd) said: "The Messenger of Allah (may Allah bless him and grant him peace) narrated it to us, and we were promised it."
