DUTY TO OTHERS H 308 "Whosoever believes in Allah and the Last Day must not inconvenience his neighbor. Whosoever believes in Allah and the Last Day must honor his guest; and whosoever believes in Allah and the Last Day should speak well or else remain silent." R 308 Bukhari and Muslim with a chain up to Abu Hurairah who related that the Prophet, praise and peace be upon him, said this.
308- وعنه : أن رَسُول الله صلى الله عليه وآله وسلم ، قَالَ : "مَنْ كَانَ يُؤْمِنُ بالله وَاليَومِ الآخرِ ، فَلاَ يُؤْذِ جَارَهُ ، وَمَنْ كَانَ يُؤْمِنُ باللهِ وَاليَومِ الآخِرِ ، فَلْيُكْرِمْ ضَيْفَهُ ، وَمَنْ كَانَ يُؤْمِنُ باللهِ وَاليَومِ الآخِرِ ، فَلْيَقُلْ خَيْراً أَوْ لِيَسْكُتْ" مُتَّفَقٌ عَلَيهِ .
