Volume 7, Book 69, Number 539:
Narrated Al-Bara’ bin ‘Azib:
Allah’s Apostle 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).
