He who believes in Allah and in the last day should honour his guest; he who believes in Allah and in the last day should not harm his neighbor; he who believes in Allah and in the last day should speak good or keep silence. (Using translation from Abū Dāʾūd 5154)
عَنْ أَبِي شُرَيْحٍ الْخُزَاعِيِّ وَكَانَتْ لَهُ صُحْبَةٌ قَالَ سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَنْ كَانَ يُؤْمِنُ بِاللهِ وَالْيَوْمِ الْآخِرِ فَلْيُكْرِمْ ضَيْفَهُ وَمَنْ كَانَ يُؤْمِنُ بِاللهِ وَالْيَوْمِ الْآخِرِ فَلْيُحْسِنْ إِلَى جَارِهِ وَمَنْ كَانَ يُؤْمِنُ بِاللهِ وَالْيَوْمِ الْآخِرِ فَلْيَقُلْ خَيْرًا أَوْ لِيَصْمُتْ
