From Sahih Bukhari (Hadith 6018):
Narrated Abu Huraira:Allah's Messenger (ﷺ) said, "Anybody who believes in Allah and the Last Day should not harm his neighbor, and anybody who believes in Allah and the Last Day should entertain his guest generously and anybody who believes in Allah and the Last Day should talk what is good or keep quiet. (i.e. abstain from all kinds of evil and dirty talk)
