Sahih al-Bukhari 5863

نَهَانَا النَّبِيُّ صلى الله عليه وسلم عَنْ سَبْعٍ نَهَى عَنْ خَاتَمِ الذَّهَبِ ـ أَوْ قَالَ حَلْقَةِ الذَّهَبِ ـ وَعَنِ الْحَرِيرِ، وَالإِسْتَبْرَقِ، وَالدِّيبَاجِ، وَالْمِيثَرَةِ الْحَمْرَاءِ، وَالْقَسِّيِّ، وَآنِيَةِ الْفِضَّةِ، وَأَمَرَنَا بِسَبْعٍ بِعِيَادَةِ الْمَرِيضِ، وَاتِّبَاعِ الْجَنَائِزِ، وَتَشْمِيتِ الْعَاطِسِ، وَرَدِّ السَّلاَمِ، وَإِجَابَةِ الدَّاعِي، وَإِبْرَارِ الْمُقْسِمِ، وَنَصْرِ الْمَظْلُومِ‏.

“The Prophet ﷺ forbade us to use seven things: He forbade using gold rings, silk, Istabraq, Dibaj, red Mayathir, Al-Qassiy, and silver utensils. He ordered us to do seven other things. To pay a visit to the sick; to follow funeral processions; to say, "May Allah be merciful to you" to a sneezer if he says "Praise be to Allah"; to return greetings, to accept invitations; to help others to fulfil their oaths and to help the oppressed ones”
