Narrated Abu Huraira:
حَدَّثَنِي عَبْدُ الْعَزِيزِ بْنُ عَبْدِ اللَّهِ ، حَدَّثَنَا إِبْرَاهِيمُ بْنُ سَعْدٍ ، عَنِ ابْنِ شِهَابٍ ، عَنْ أَبِي سَلَمَةَ ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيَقُلْ خَيْرًا، أَوْ لِيَصْمُتْ، وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلاَ يُؤْذِ جَارَهُ، وَمَنْ كَانَ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الآخِرِ فَلْيُكْرِمْ ضَيْفَهُ " .
Allah's Messenger (ﷺ) said, "Whoever believes in Allah and the Last Day should talk what is good or keep quiet, and whoever believes in Allah and the Last Day should not hurt (or insult) his neighbor; and whoever believes in Allah and the Last Day, should entertain his guest generously."
