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.
سَمِعْتُ الْبَرَاءَ بْنَ عَازِبٍ ؓ يَقُولُ نَهَانَا النَّبِيُّ ﷺ عَنْ سَبْعٍ نَهَى عَنْ خَاتَمِ الذَّهَبِ أَوْ قَالَ حَلْقَةِ الذَّهَبِ 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
