The Messenger of Allah ﷺ said, "Whoever believes in Allah and the Last Day must not harm his neighbor. Whoever believes in Allah and the Last Day must honor his guest. And whoever believes in Allah and the Last Day must speak good or remain silent."
قال رسول الله ﷺ: من كان يؤمن بالله واليوم الآخر فلا يؤذ جاره، ومن كان يؤمن بالله واليوم الآخر فليكرم ضيفه، ومن كان يؤمن بالله واليوم الآخر فليقل خيرا أو ليصمت.
Bukhari (6018) and Muslim in the Book of Faith (47/75) both narrated it through Abu Ahwas, from Abu Husayn, from Abu Salih, from Abu Hurairah, who mentioned it.
