The Prophet ﷺ ordered us to do seven (things) and forbade us from seven (other things): He ordered us to pay a visit to the sick, to follow funeral possessions, to say: May Allah be merciful to you to a sneezer, - if he says: Praise be to Allah, to accept invitation (invitation to a wedding banquet), to return greetings, to help the oppressed, and to help others to fulfill their oaths (provided it was not sinful). And he forbade us from seven (things): to wear golden rings or golden bangles, to wear silk (cloth), Dibaj, Sundus and Mayathir.  

أَمَرَنَا النَّبِيُّ ﷺ بِسَبْعٍ وَنَهَانَا عَنْ سَبْعٍ أَمَرَنَا بِعِيَادَةِ الْمَرِيضِ وَاتِّبَاعِ الْجِنَازَةِ وَتَشْمِيتِ الْعَاطِسِ وَإِجَابَةِ الدَّاعِي وَرَدِّ السَّلاَمِ وَنَصْرِ الْمَظْلُومِ وَإِبْرَارِ الْمُقْسِمِ وَنَهَانَا عَنْ سَبْعٍ عَنْ خَاتَمِ الذَّهَبِ أَوْ قَالَ حَلْقَةِ الذَّهَبِ وَعَنْ لُبْسِ الْحَرِيرِ وَالدِّيبَاجِ وَالسُّنْدُسِ وَالْمَيَاثِرِ
