We were sitting in the company of Hudhaifa who asked for water and a Magian brought him water.
But when he placed the cup in his hand, he threw it at him and said, "Had I not forbidden him to do so
more than once or twice?" He wanted to say, "I would not have done so," adding, "but I heard the
Prophet saying, "Do not wear silk or Dibaja, and do not drink in silver or golden vessels, and do not
eat in plates of such metals, for such things are for the unbelievers in this worldly life and for us in the
Hereafter."
Sahih al-Bukhari Book 70, Hadith 54
