The Prophet ﷺ said, "Whoever believes in Allah and the Last Day, should serve his guest generously; and whoever believes in Allah and the Last Day, should unite the bond of kinship (i.e. keep good relation with his kith and kin); and whoever believes in Allah and the Last Day, should talk what is good or keep quiet."
عَنِ النَّبِيِّ ﷺ قَالَ مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيُكْرِمْ ضَيْفَهُ وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيَصِلْ رَحِمَهُ وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيَقُلْ خَيْرًا أَوْ لِيَصْمُتْ
