صحيح البخاري

Narrated `Abdur-Rahman bin Abi Laila:

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."
