Narrated Al-Bara' bin `Azib:
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).
حَدَّثَنَا مُوسَى بْنُ إِسْمَاعِيلَ، حَدَّثَنَا أَبُو عَوَانَةَ، عَنِ الأَشْعَثِ بْنِ سُلَيْمٍ، عَنْ مُعَاوِيَةَ بْنِ سُوَيْدِ بْنِ مُقَرِّنٍ، عَنِ الْبَرَاءِ بْنِ عَازِبٍ، قَالَ أَمَرَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم 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 ـ أَوْ قَالَ آنِيَةِ الْفِضَّةِ ـ وَعَنِ الْمَيَاثِرِ وَالْقَسِّيِّ، وَعَنْ لُبْسِ الْحَرِيرِ وَالدِّيبَاجِ وَالإِسْتَبْرَقِ.
