Sahih al-Bukhari Book 74, Hadith 60
(the wife of the Prophet) Allah's Messenger (ﷺ) said, "He who drinks in silver utensils is only filling his
`Abdomen with Hell Fire."
The Prophet (ﷺ) said, "Do not drink in gold or silver utensils, and do not wear clothes of silk or Dibaj, for these things are for them (unbelievers) in this world and for you in the Hereafter."
Allah's Messenger (ﷺ) ordered us to do seven things and forbade us from seven. He ordered us to visit the sick, to follow funeral processions, (to say) to a sneezer, (May Allah bestow His Mercy on you, if he says, Praise be to Allah), to accept invitations, to greet (everybody), to help the oppressed and to help others to fulfill their oaths. He forbade us to wear gold rings, to drink in silver (utensils), to use Mayathir (silken carpets placed on saddles), to wear Al-Qissi (a kind of silken cloth), to wear silk, Dibaj or Istabraq (two kinds of silk).
