Shama-il Tirmidhi Chapter 028, Hadith Number 001 (186).

Thaabit radiyallahu anhu relates that Anas radiyallahu anhu showed us a large wooden cup, which was lined with metal, and said, O’ Thaabit, this is the cup of Rasoolullah sallallahu alaihe wasallam.

Commentary
It is said that this cup was sold from the estate of Sayyidina Nadr ibn Anas radiyallahu anhu for eight lakh Dirhams and Imaam Bukhari drank water from it in Basrah. Some say that, that was another cup.
