Narrated Ibn Abi Laila:
While Hudhaifa was at Al-Madain, he asked for water whereupon the chief of the village brought him water in a silver cup. Hudhaifa threw it at him and said, "I have thrown it only because I have forbidden him to use it, but he does not stop using it. Allah's Apostle said, 'Gold, silver, silk and Dibaj (a kind of silk) are for them (unbelievers) in this world and for you (Muslims) in the hereafter.'
