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."  

خَرَجْنَا مَعَ حُذَيْفَةَ وَذَكَرَ النَّبِيَّ ﷺ قَالَ لاَ تَشْرَبُوا فِي آنِيَةِ الذَّهَبِ وَالْفِضَّةِ وَلاَ تَلْبَسُوا الْحَرِيرَ وَالدِّيبَاجَ فَإِنَّهَا لَهُمْ فِي الدُّنْيَا وَلَكُمْ فِي الآخِرَةِ  

(the wife of the Prophet) Messenger of Allah ﷺ said, "He who drinks in silver utensils is only filling his ʿAbdomen with Hell Fire."  

عَنْ أُمِّ سَلَمَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ الَّذِي يَشْرَبُ فِي إِنَاءِ الْفِضَّةِ إِنَّمَا يُجَرْجِرُ فِي بَطْنِهِ نَارَ جَهَنَّمَ  

Messenger of Allah 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).  

أَمَرَنَا رَسُولُ اللَّهِ ﷺ بِسَبْعٍ وَنَهَانَا عَنْ سَبْعٍ أَمَرَنَا بِعِيَادَةِ الْمَرِيضِ وَاتِّبَاعِ الْجِنَازَةِ وَتَشْمِيتِ الْعَاطِسِ وَإِجَابَةِ الدَّاعِي وَإِفْشَاءِ السَّلاَمِ وَنَصْرِ الْمَظْلُومِ وَإِبْرَارِ الْمُقْسِمِ وَنَهَانَا عَنْ خَوَاتِيمِ الذَّهَبِ وَعَنِ الشُّرْبِ فِي الْفِضَّةِ أَوْ قَالَ آنِيَةِ الْفِضَّةِ وَعَنِ الْمَيَاثِرِ وَالْقَسِّيِّ وَعَنْ لُبْسِ الْحَرِيرِ وَالدِّيبَاجِ وَالإِسْتَبْرَقِ
