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. (ie abstain from all kinds of evil and dirty talk).
We can also learn from this hadith that being a believer means more than just saying words of faith; it requires action as well. Our actions must reflect our beliefs if we want to truly honor Allah SWT and His Messenger ﷺ .
