H 309 "Whosoever believes in Allah and the Last Day should be kind to his neighbor. Whosoever believes in Allah and the Last Day should honor his guest; and whosoever believes in Allah and the Last Day should speak well or remain silent." R 309 Muslim with a chain up to Abu Shuraih Khuza'I who related that the Prophet, praise and peace be upon him, said this.
309- وعن أَبي شُرَيْح الخُزَاعيِّ رضي الله عنه : أن النَّبيّ صلى الله عليه وآله وسلم ، قَالَ : "مَنْ كَانَ يُؤمِنُ بِاللهِ وَاليَومِ الآخِرِ ، فَلْيُحْسِنْ إِلَى جَارِهِ ، وَمَنْ كَانَ يُؤْمِنُ باللهِ وَاليَومِ الآخِرِ ، فَلْيُكْرِمْ ضَيْفَهُ ، وَمَنْ كَانَ يُؤْمِنُ بِاللهِ وَاليَومِ الآخِرِ ، فَلْيَقُلْ خَيْراً أَوْ لِيَسْكُتْ" رواه مسلم بهذا اللفظ ، وروى البخاري بعضه .
