Sunan Abi Dawud, Hadith 5135

Abu Hurairah reported the Messenger of Allah (May peace be upon him) as saying: 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.

حَدَّثَنَا مُحَمَّدُ بْنُ الْمُتَوَكِّلِ الْعَسْقَلاَنِيُّ، حَدَّثَنَا عَبْدُ الرَّزَّاقِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ أَبِي سَلَمَةَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيُكْرِمْ ضَيْفَهُ وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلاَ يُؤْذِ جَارَهُ - وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيَقُلْ خَيْرًا أَوْ لِيَصْمُتْ ‏" ‏ ‏.‏
