The Prophet ﷺ said, "Whoever believes in Allah and the Last Day, let him be good to his neighbor. Whoever believes in Allah and the Last Day, let him honor his guest. And whoever believes in Allah and the Last Day, let him speak good or remain silent."
أن النبي ﷺ قال: من كان يؤمن بالله واليوم الآخر فليحسن إلى جاره، ومن كان يؤمن بالله واليوم الآخر فليكرم ضيفه، ومن كان يؤمن بالله واليوم الآخر فليقل خيرا أو ليسكت.
Muslim narrated it in the Book of Faith (48) through several routes from Sufyan bin Uyayna, from Amr, that he heard Nafi bin Jubayr relate from Abu Shurayh Khuzai, and he mentioned it. Bukhari narrated it in the Book of Raqaiq (6476) through another route from Abu Shurayh with similar wording.
